Do your headlights meet DOT standards, are they legal for use in the USA, Canada, and Mexico?

Excellent question, YES, they are! We are proud to say that any of our products labeled as “FMVSS/CMVSS 108 legal” have been completely designed from the ground up by a dedicated team of greasy gear heads & degreed mechanical and optical engineers with a combined 50 years of engineering experience. What this means is that our headlights are legal for use in the US, Canada, Mexico, and any other country that recognizes and allows DOT lighting products. Please note, the DOT does not approve any product, they only set the testing standards and enforce those standards through the NHTSA ODI division. So, any headlight manufacturer that says their lights are “DOT Approved” is simply using buzz words for marketing purposes.

YES, we designed and tested our lights to meet or exceed the various SAE standards set forth such as J1383 and J578, but please note, the SAE does not issue approvals so there is no formal SAE approval we can obtain. Any lighting brand that says their lights are SAE approved is just using that as gimmicky marketing material.

Unfortunately, NO, our headlights were developed to meet DOT standards for use in the US, and any other country that accepts DOT Right Hand Drive (RHD) lights for on-road use. They are not marked with an E-mark and cannot be legally used on-road in countries that require ECE certification.

Unfortunately, NO, our headlights were developed to meet DOT standards for use in the US, and any other country that accepts DOT Right Hand Drive (RHD) lights for on-road use. They should never be used in countries that are Left Hand Drive (LHD) since the hot spot is incorrectly positioned for LHD applications.

NO they do not, if that is what you want than we recommend projector or matrix lighting technology since those will produce a crisp horizontal light/dark cutoff line. We purposely did not utilize this technology since it would have destroyed the classic Fresnel aesthetics of the lens, and because projectors produced inferior light output when installed within a standard sized headlight housing. Our headlights have a very wide horizontal cutoff with a well-defined hot spot for down road illumination that slowly transitions to dark above the H cutoff line. Many people prefer this as it offers slight illumination above the cutoff for things like street signs, while at the same time not exceeding FMVSS 108 limits or blinding oncoming drivers.

Not yet but very soon! We are currently developing the smaller classic H5001 & H5006 5 ¾” (146mm) round light that is found in many classics, after that the next headlights we will develop will be the rectangular models. These will take time, but the result will be the best performing 100% classic OE looking LED headlights available in the market.

YES, these were designed to meet or exceed the FMVSS 108 S14.5.1 vibration requirements for light vehicles and motorcycles. NOTE: These are designed with a 9V cutoff voltage, so they may not be compatible with some motorcycle headlight modulators, to prevent flickering the modulator may have to be disabled. In addition, if your motorcycle vibrates excessively due to engine or suspension modifications it may result in shorted LED or driver circuit life due to excessive frame and handlebar vibration outside of normal gRMS design specifications.

YES, we offer two light colors to suit your particular style, a 2,900K Classic White and a 5,800K Modern White with clear lenses, both of these meet the FMVSS 108 S10.4 strict legal requirements for the color white.

Honestly, it’s a matter of personal preference. Both light colors produce the exact same lumen output, but we find that most people say the 5,800K appears brighter than the 2,900K light due to the way the human eye reacts to the 450nm spike in the LED’s color spectrum. Our general recommendation is if you have a restomod, prefer a more modern look, or want a light that makes things “pop” at night go with the 5,800K Modern White. If your vehicle is all original, you want to retain the original halogen color look at night, or if you’re not a fan of the “bright white” light then go with the 2,900K Classic White. Either light is great, and the choice is ultimately yours; the only difference is the hue and your personal preference.

Our Cruisader headlights use our patent pending LED quad beam technology. What makes them special is that we use (4) separate high power LEDs combined with (4) integrated parabolic reflectors, whereas standard halogen lights use a single filament and single parabolic reflector. Utilizing optical ray tracing software, we precisely designed the dimensions of the four parabolic reflectors to combine all four beams into our OE looking curved Fresnel lens to produce the focused low and high beam patterns you see produced on the road.
Easy, optical engineering expertise, quality workmanship, and the fact that we don’t use cheap components. Our headlights have a refined and balanced beam pattern not seen in any other classic OE light in the market, we only use top quality materials, we make our cast components from precision steel molds instead of defect prone aluminum molds, our lens is UV hard coated with the same coating used in many European vehicles, and our LEDs are made to our own in-house spec with high CRI ratings. The cheap headlights you see online have none of these features which is why so many people are amazed when they install our headlights and go out on their first drive at night. Most tell us it’s like driving a modern-day vehicle, and are ecstatic that they can actually see without blinding other drivers!

That depends, but why is because of each person’s unique eyesight. This is why we specify illumination distances by various industry standard lux values. We set our maximum illumination distance at 1 lux, which equates to over 700’ with our low beam. For most people 3 lux, which is equal to nighttime twilight, is a very comfortable illumination level at night, which our headlight will produce to approximately 425’. For comparison, most halogens and inexpensive LED headlights will only illuminate to 3 lux at 200’ or less. This means that you see twice as far with our headlights and have a wider beam pattern as well. This may not seem like much, but assume you’re cruising down a two-lane road at 65 MPH, this equates to travelling at 95 ft/sec. Now image it’s a pitch-black night and there’s something in the middle of the road, what our lights offer is over 2 seconds of extra reaction time for you to see, react, and not hit what’s in the road, which could save damaging your car, hitting another car, or losing your life!

None at all, our lights are manufactured to a 1:1 size to match industry standard 7” round H6024 external dimensions to comply with FMVSS 108 S10.13 requirements, and they use a standard H4 plug with no silly pigtail to have to deal with. This means that they will fit into all housings. We do have to add one stipulation, we haven’t been able to install them in every model vehicle, but during the development phase we test fit them in over two dozen different vehicle models and did not find one that they will not directly fit in.

YES, 100%. Anytime a forward mounted light is replaced the beam pattern must be checked and re-aimed, this ensures that you not only have the best illumination, but that you do not potentially cause undue glare to oncoming drivers from lights aimed too high.

Our lenses are made from polycarbonate with an OEM grade UV hard coating. Our initial design target was to make the lenses from borosilicate glass, but after many design iterations we found that even German made glass mold/cutting equipment was not able to produce a glass lens capable of creating an acceptable beam pattern. Our polycarbonate lenses exceed FMVSS 108 S14.6.12 photometry requirements, and to prevent yellowing are coated with an OEM grade UV hard coat which will endure multiple years in direct sunlight with no visible deterioration. The best part is our classic style Fresnel lens retains the aesthetics and originality your vehicle demands, which you won’t find in most of our LED competitors.

We offer our lights individually for those who only need one light, for most vehicle owners you will need two, so be sure your cart contains two before checking out!

Do your 7” headlights have a high and low beam?
Of course they do, to comply with FMVSS 108 regulations they must, no surprises here.

NO, although they are a sealed assembly, our housing incorporates a semi-permeable seal for venting water vapor which means that they are not rated for indefinite submersed or underwater use like a true Sealed Beam lamp. We rate these lights as IP67 which means they will resist temporary submersion in water for up to 30 minutes, they cannot be used in a continuous submersion environment.

We designed our lights with a Visually Optically Aimed (VOL) beam pattern with no kink, this produces a bright RHD hot spot, a wide 80+ degree beam pattern, a flat horizontal cut-off line, and balanced foreground illumination.
These were designed to work on 12V DC vehicles, and we recommend a continuous voltage of 11.0V – 15.0V DC for optimal performance.

YES, but not directly. If you have an older vehicle which operates on 6V DC these will not turn on. In order for them to operate in a 6V DC system you will need to add an external 6V to 12V DC step-up converter to the positive input wire of your headlight switch. Although we wanted these to operate on 6V DC, we had to eliminate that criteria early in the design phase due to housing volume limitations and thermal management restrictions. Step-up converters are very inexpensive and can be found online or at electronic sites, but it would have to be sourced and properly wired by you.

YES, these will directly work with your vehicle; you do not need to rewire anything. We purposely designed our LED driver circuit to be non-polarity. What this means is that you can reverse the ground and positive connections and the headlight will still function normally on both the low and high beam, pretty cool feature, huh?

Simple, aesthetics and packaging constraints. During the initial development phase, we considered four technology options, Reflector, Projector, Total Internal Reflection (TIR), and Matrix. Reflector technology allowed us to achieve the lens look and exterior dimensions we needed, but the tradeoff was a cutoff line not as sharp as other technologies. Our Projector prototype resulted in a great cutoff line but it was a buggy eye looking modern light and the rear housing was too deep, this was because a 2.5” projector was required for decent beam output. Our TIR design might have achieved a correct exterior dimension, but our lens would not look aesthetically pleasing since it would have required 2 separate TIR lenses within the same housing with 2 LED sources, one for the low and one for the high beam. Finally, matrix technology would have achieved the best output, but the lens would have looked way too futuristic and the lights would have required complicated external components to operate.
Our housings are made from solid aluminum alloy, and the reflector surface is coated with 99.9% pure aluminum applied by a vapor deposition process. This combination was specifically selected to achieve exceptional thermal transfer from the LED module to the housing and to ensure optimal reflectivity.

NO, sometimes they are needed; but we did not want this as a potential failure mode, so we utilized passive cooling technology to maintain our LED junction temperatures. We accomplished this by the use of a thermal tube, a large LED module base, thermal pastes, a robust solid aluminum reflector housing, and our active temperature control circuit.

Our optical axis aiming mark is a 3mm circle placed on the surface of the aluminum light shield within the light, this is to comply with FMVSS 108 S10.18.5.1 requirements, this circle is the sole marker to be used for VOL aiming. If the mark is too difficult to see and you want to use the lens, this VOL mark aligns with the top left line of the letter K in our logo, approximately 2mm to the right of the knight’s helmet.

This is a loaded question because brightness means nothing without a well-designed beam pattern and illumination distribution analysis. For those that want to just know the maximum brightness, each of our H6024 7” classic lights produce 775 lumens on low and 1,350 lumens on high under standard ambient operating conditions. The main beam hot spot is 52,000 cd on low and 64,000 cd on high. Lumens, lux, and candela (cd) are all different and are often confused, if you’re not aware of the differences please see the bullet point below this for clarity.

Great question, the main thing to understand is that lumen (lm) and candela (cd) have no distance factors, while lux (lx) does. When a manufacturer lists a lumen specification all they are telling you is how much light is produced. At KnightBeam, we specify our output as the actual light exiting the lens, which we feel is the most honest and accurate representation of the light output. Many other manufacturers list either the overall or the theoretical light output from the filament or LED. Using this value is not entirely accurate since the only output you as a driver perceive is what is coming out of the lens. This is why you see astronomical numbers like 60,000 lumens or more advertised from many Amazon and eBay sellers. Candela and lux both indicate how much a surface is illuminated, for a headlight, the surface you care about is the road. When lux is listed it must be in conjunction with a distance, whereas candela does not have a distance factor, this is why candela is the best measurement to accurately document and compare light output. To convert from candela to lux the formula is lux = (candela)/(distance)2, what this means is that every time the distance from the light source doubles the lux will reduce by a factor of 4. The important takeaway is if a distance is not included with the advertised lux value, the number supplied is absolutely meaningless, whereas candela can be listed without a distance.

NO, but we will share some. It took years and countless hours of R&D to design, test, and revise our design. We will share some of the test data but not all, as much of it contains sensitive Intellectual Property (IP) which if shared would offer our competitors free R&D.

25 watts on low/35 watts on high, well below any halogen or High Intensity Discharge (HID) bulb out there.

Depending on your vehicle’s alternator voltage output, each headlight will require 2.1-3.5 amps of continuous power (or 4.2-7.0 amps per set), we recommend a minimum fuse rating of 5 amps per headlight light or 10 amps if on a single fused circuit. Our lights utilize a self-regulating driver system which will increase or decrease amperage draw depending on the input voltage, so please ensure your grounds are clean for the best performance.

NO, all vehicles with original H6024 bulbs utilize wires and circuits rated for 7.5-15 amps per headlight. The Cruisader LED headlights consume less than 4 amps, therefore no changes, relays, or wiring modifications are needed.

MAYBE, since these consume 25/35 watts most vehicles will not have an issue and will not illuminate a burned-out warning lamp, but some vehicles which are very sensitive to wattage changes on the headlight circuit may trigger the warning lamp. In the event a warning lamp illuminates you would need to install an inline resistor pack to the light to eliminate the warning lamp.
What is your warranty period?
12 months (1) year from the date of purchase or registered installation date. If you wonder why we don’t offer a Lifetime warranty it’s because most companies Lifetime warranties aren’t worth the paper they’re written on, and we’re not going to do the same thing just to give you the “warm & fuzzies”. We know from our design and rigorous testing that if a failure occurs from either a defective component or assembly process the failure will appear within the first few hours of use and will be covered under our 1 year warranty. If after 1 year the light doesn’t fail, it likely won’t. People familiar with reliability calculations and Weibull analysis will understand this and why we’ve set our warranty to 1 year. In the rare event our product fails after 1 year please reach out to us as we want to ensure your satisfaction and may want to obtain the failed product for engineering analysis or continual improvement activities.
Simply, lens breakage and any damage due to physical abuse, modification, or accident is not covered, please see our comprehensive limited warranty for specific details.

We also offer FREE products to companies/online influencers in exchange for honest reviews. If interested please fill out a submission in our Contact Us page.
Great question, very simply because we make a great high-quality product. In addition, we’re a family business in California USA with skilled engineers and regular car people that designed these. We’re not some faceless corporate conglomerate looking at just profit margins or a clueless greedy business person that makes a product but has no fundamental engineering or quality background.
They are physically assembled in China. Long story, they were designed in the USA and made from materials and tooling from the USA, Japan, China, Taiwan, and Germany. As much as we would have loved to make these in-house, we had to outsource them to keep prices reasonable. What we guarantee is that the folks that we paired with in China are some really great people on normal 8-5 Monday-Friday schedules, make OEM products, have a high level of quality, and have taken great pride in this product to make it the best it can be!
