**These bulbs are intended for off-road use only in motorcycle, ATV, Snowmobile, and race applications.** Our High-Performance Bulbs are 3.5 times brighter than halogen bulbs, delivering 3400 lumens of usable light and a high beam that reaches over 300 meters at 1 lux (lab tested in a standard 7” round headlight housing)! The 6000K bright-white color temp enhances visibility and turns night into day. A built-in heat sync improves cooling while increasing beam performance and bulb lifespan. The compact 29x50mm (1x2 inch) external driver box will fit in a wide range of vehicles. And last but not least, our unique aiming system allows rotational adjustment of our bulbs to ensure the proper horizontal alignment across an infinitely diverse range of OEM headlight housings. Fitment Note: Bulb housing and space vary by model. Measure the available space around your factory headlight bulb before purchasing. For tight spaces, choose our SureFit bulbs which match the size and shape of your factory halogens. Be Smart When Choosing LED Bulbs. Not all LED bulbs are built to the same standard and many options from careless manufactures can be downright dangerous - throwing stray light all over the road that can distract other motorists. We have painstakingly engineered and tested our bulbs to ensure that they maintain a crisp cut-off, where intended, and direct the light only where it should be. That said, it is not feasible to test and certify our bulbs in every possible headlight housing available. For that reason, the bulbs do not meet the FMVSS108 standard for use in on public roadways. These bulbs are intended for off-road use only in motorcycle, ATV, Snowmobile, and race applications. Top Bin Cree LEDs High power LEDs generate 3400 lumens of usable light. That 3.5x more lumens than standard halogen bulbs. Proprietary Housing Design Our proprietary die-cast housing and driver box design keeps the LEDs cool to maximizes light output while maintain a low-profile form factor that will fit most factory applications. Precision Beam Denali bulbs feature a proprietary housing geometry that perfectly mimics the position and orientation of a halogen filament. This allows us to significantly crank up the beam intensity without distorting the proper beam shape. Rotational Aiming SystemOur unique aiming system allows rotational adjustment of our bulbs to ensure the proper horizontal alignment in the widest variety of OEM bulb housings. 6000K Color Temp Our bright white color temp will give your vehicle a modern look while increasing visibility, helping you see farther and react sooner in low-light conditions. 5 Year Warranty Don't waste your money on cheap LED bulbs that won't even last a full riding season. We stand behind the quality of our bulbs with an industry-best 5-year warranty.
