Overview
Upgrade. Add dual-color functionality and a modern appearance to your front turn signals with the 4257 HP24 turn signal bulb. Populated with sixteen amber chips and eight white chips this bulb lights up white when your headlights are turned on and flashes amber when the turn signals are activated. Housed in an aluminum casing for maximum heatsinking properties the HP24 will last for years to come. Best of all installation only takes minutes - simply take out your factory bulb and the HP24 will fit snugly in the socket.
The 4257 HP24 Switchback bulb features a custom-molded base connector making it a true replacement for factory incandescent 4257-size front turn signal bulbs. Unlike a 3157 bulb that includes tabs on either side of the bulb a 4257 bulb does not. The 4257 HP24 Switchback bulb is compatible with Ford vehicles using a dual-filament 4257-size front turn signal bulb with a clear reflector lens.
Brightness. At 410 lumens the HP24 will provide about double the total light output compared to 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.
Reliability. Unlike other bulbs on the market this bulb is built with constant-current circuitry along with transient suppression meaning this bulb will last for years to come.
