The Diode Dynamics 3157 XP80 LED is a direct replacement for 3156/3157 tail light and rear turn signal bulbs, engineered as the brightest self-contained automotive LED bulb in its class. With sixteen 5W LEDs and an aluminum heatsink it delivers about 510 lumens for much greater output and a modern appearance while fitting snugly in the factory socket. The inductive constant-current drive, transient suppression and durable housing improve longevity, and a three-year replacement warranty backs the product.
