H11B LED Headlight Kits
H11B looks almost identical to a standard H11, but it is not the same bulb — and that catches a lot of people out. The H11B has a differently keyed base (the locating tab sits in a different spot), so a regular H11 won’t seat and orient correctly in an H11B socket. H11B is used on select Ford, Mazda, and Lincoln models, typically as the low beam.
Get the right base, or the beam is wrong
Because the base keying is different, using the wrong one either won’t lock in or will hold the emitter at the wrong angle, throwing your beam off. So the single most important step here is confirming you actually need H11B (not H11). The Year/Make/Model finder at the top of the page does exactly that — enter your vehicle and we’ll give you the correct H11B LED kit that locks in and aims right.
Once you have the right base, the rest is standard: it’s a plug-and-play swap, best in projector housings, with proper cooling for lifespan. Free shipping over $75, lifetime warranty, 50,000+ reviews since 2004.
Frequently asked questions
Is H11B the same as H11?
No. They look similar but the H11B has a differently keyed base, so they are not interchangeable. An H11 will not seat or orient correctly in an H11B socket. Always match the exact size your vehicle uses.
Can I use an H11 bulb instead of H11B?
It is not recommended. The base keying differs, so an H11 either will not lock in or will hold the LED at the wrong angle, giving you a poor beam pattern. Use an H11B kit for an H11B vehicle.
Which vehicles use H11B bulbs?
H11B is used on select Ford, Mazda, and Lincoln models, most often as the low beam. Because it is easy to confuse with H11, confirm your exact size with the Year/Make/Model finder before ordering.
How do I know if I need H11B or H11?
Check the base of your existing bulb or, more simply, enter your vehicle in the Year/Make/Model finder at the top of the page. It will tell you exactly which one your car takes for each position.
