Are you sick of relying on dull, yellow Halogen lights that barely light up the road and give your vehicle an outdated and cheap look?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, full Canbus, error and flicker free 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 9012 HB4 LED kit was designed to offer the best light pattern for reflector style headlights. 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 bulbs 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.
SUPERIOR & SAFER THERMAL MANAGEMENT
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.
EASY & FAST INSTALLATION
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.

SPECS AT A GLANCE…
I was a little hesitant at first about the cost of upgrading my lights but wow I am so glad I did. I drive 500-600 miles a day 5 days a week and found my stick halogen lights just weren’t bright enough. I changed my low beams to the 60w LED and my fog lamps to the 40w LED and I can see great and don’t even use high beam anymore. What a difference these LEDs are easy to install with a nice crisp clean projection. I love them and only sorry I didn’t do this sooner. Danny was a great wealth of knowledge and made this a quick easy decision.
How bright are these fog lights? let me tell you a story. I was having a new grille put in my grand cherokee and i asked the shop to swap out these bulbs, and the headlight bulbs while they had the bumper off. the shop swapped the plugs around on the headlights so they wouldn't turn on. I didn't actually realize that at first, because i had the fogs on and they lit up the ground like it was 8 AM, not 8 PM
Easy to install plug and play. Zip ties work with headlight but foglights have nothing to zip tie to so need some tape if u wanna keep it secure. DRLS do not flicker at all. Light output is very good but not great like my HIDS b4
I installed the low beams. They are a Huge improvement over the stock halogens on my 2017 Ram 1500 SLT. Literally, night and Day.
Very happy with these bulbs in my 2016 Ram 1500 and very happy with the customer service. Fog lights and high beams are next.
