Add a modern appearance to your vehicle with the H1 COB12. The COB12 LED upgrades the factory yellowish incandescent bulb to a modern cool white appearance. Best of all, installation only takes minutes - simply take out your factory bulb and the COB12 will fit snugly in the socket. The COB12 is a cosmetic upgrade only and will provide the same light output as your factory bulb. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare. The COB12 is a great option for your fog lights or daytime running lights (DRL). We don't recommend using the COB12 in any low beam or high beam headlight applications. Unlike other bulbs on the market, Diode Dynamics LEDs are built with constant-current inductive circuitry, along with transient suppression. While more expensive than simple bulbs, this allows Diode Dynamics LEDs to last for years, with no flickering or failure. And like every Diode Dynamics product, it's backed by an industry-leading three-year replacement warranty. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting. Unlike every other LED distributor, we assemble and engineer products ourselves in the United States, for high quality and fast time-to-market of the newest and brightest LED technologies. We pride ourselves in offering only quality LED products, that will exceed your expectations. Please contact us if you'd like to discuss your lighting project!
