Are you sick of relying on dull, yellow Halogen lights that barely light up the road and give your vehicle an outdated and cheap look?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 H4 LED headlight 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 H4 LED kit was designed to offer the best light pattern for reflector-style headlights. This bulb replacement does low and high beam. This LED is the slimmest LED on the market, not only the shortest but the thinnest as well. 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.
UNMATCHED BRIGHTNESS & PRECISION
You’ll be hard-pressed to find a brighter, more efficient LED bulb on the market! Designed here in the USA, these H4 LED headlight bulbs to feature an impressive 6 CSP LED chip design. They are 40 watts, 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.
LONG LASTING & RELIABLE DESIGN
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.

Solid one-piece silicone aluminum 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.

Their easy-to-use plug-and-play design, 360 degrees rotating collar, and petite in-line driver, which mean you’ll be able to effortlessly upgrade your headlights.
SPECS AT A GLANCE…
Pretty impressed, even for the price. I hope they last because they are a huge improvement and had a good cutoff which made them easy to adjust. Got the 60w low beams for a coworker of mine we call “coach” who was having trouble seeing on the dark country roads. He’s pretty happy which makes me glad I did the research and found quality parts rather than being lazy/cheap and picking him up some chinesium junk on Amazon. Might have to get some for my truck.
Great customer service and advice-' talked me through needs and best option for my 2015 Ram. The bulbs are a huge improvement and work flawlessly. Easy installation.
Great Price, Brighter than the Sun!
Fit my 11 Ram perfectly. Had to rotate 180 as didn’t work first time.
Now I can see. Extremely bright. More lummes than headlights.
these are real bright, I would recomend these to any one.
Love the product so far.
I originally purchased the wrong lights. I'm not a big fan of conversing by email, but your rep was very helpful in getting me the correct part. He responded to my email immediately. Thank you.
These fogs finish the look perfectly and covers all the little creatures that might dart out of the sides.
These bad boys really make a difference at night.
Danny as always was professional and polite.
