Are you sick of relying on dull, yellow Halogen lights that barely light up the road and give your vehicle an outdated and cheap look? If so, you’ll love this innovative, plug and play, LED Upgrade Kit!

Whereas most LED upgrade bulb options are bulky, hard to install, unreliable, and disappointingly dull, you won’t experience that with Underground Lighting. Our M9 LED kit was designed to offer the best light pattern and projection for projector style headlights. Does that mean this LED will only work for projector housing? No! This LED will work just as well in a reflector housing. We designed the LED chips to be in the perfect position to minimize glare to on-coming traffic and focus all the light where you need it… on the road! This kit is easy to install, reliable and backed by our 2 Year Warranty.


You’ll be hard pressed to find a brighter, more efficient LED bulb on the market! Designed here in the USA, these bulbs feature an impressive csp chip design. They are 50 watts per set, pure white, and offer the highest LED output of their kind. Using ray tracing technology to minimize glares, they produce a functional pattern of light by precisely focusing each ray and enhancing the hotspot for clearer, farther-reaching illumination.


With superior heat dissipation abilities that help maximize their lifespan, these bulbs are designed with longevity in mind! This means that unlike cheap competitors that burn out fast, you can count on these bulbs to last many miles. Plus, because they’re crafted from premium silicone aluminum materials and are 100% corrosion resistant, they’re sure to withstand normal wear and tear as well as the elements.


All-in-one housing design, and dual ball fan, these bulbs are specially designed to regulate their temperatures to prevent and reduce overheating at all times. But what if they overheat? The built-in temperature sensor will immediately lower the output power, restoring full brightness once the temperatures have safely stabilized.


Installing your bulbs couldn’t be easier! This kit is designed to be conveniently compact, eliminating the need for any cutting, and fits comfortably inside virtually all headlight housings. Their easy to use plug and play design, 360 degrees rotating collar, and petite in-line driver, mean you’ll be able to effortlessly upgrade your headlights.
