Features Direct replacement for factory incandescent bulb. Increased output with LED Appearance. Automotive-grade LEDs for superior performance. Plug and play, simple installation. Overview Add a modern appearance to your vehicle with the HP48. Populated with 48 Epistar 3014 LED chips, the HP48 upgrades the factory yellowish incandescent bulb to a modern cool white appearance. Thanks to the cap on the top, the light output is directed backwards and away from the bulb, instead of straight out. This allows the light output to shine much more uniformly. Best of all, installation only takes minutes - simply take out your factory bulb and the HP48 will fit snugly in the socket. Unlike other bulbs on the market, this bulb is built with constant-current circuitry, along with transient suppression. That means this bulb will last for years, not months, with no flickering or failure. And like every Diode Dynamics product, it's backed by an industry-leading three-year replacement warranty. NOTE: LED bulbs are legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. International legality varies by country.
