Upgrade. Add a modern appearance to your vehicle with the 1157 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. A diffused PC lens surrounds the LED chips, allowing 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. Brightness. At 250 lumens, the HP48 will provide slightly more light output compared to your factory bulb. If you are looking to increase output, we'd recommend checking out our HP11 and XP80 options! 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. Reliability. 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 . Experience.
