| Bulb Type | Turn Signal Light Bulb |
Product Overview. The Diode Dynamics Red LED Bulbs; 3157 XP80 upgrade the rear turn signals of the Jeep Grand Cherokee with modern LED technology, delivering instant on/off illumination for enhanced signaling response and a contemporary aesthetic. Designed as a direct OEM replacement, these bulbs provide consistent performance in the factory socket without requiring modifications.
Construction and Appearance. Built with sixteen high-power 5W LEDs arranged omni-directionally, these bulbs feature a durable metal heatsink for efficient thermal management and long-lasting operation. Their design includes inductive constant-current circuitry coupled with transient voltage suppression, ensuring stable output and resistance to electrical stress. The finish is a robust metal housing with a red lens to match the factory taillight requirements precisely.
Installation. Installation is straightforward and requires no vehicle modification; the bulbs are plug-and-play for the factory 3157 rear turn signal socket. To prevent hyperflashing caused by low LED current draw, installation of a compatible LED resistor kit, connected to the vehicle’s turn signal wiring, is recommended.
Warranty. This product carries a three-year limited replacement warranty, providing confidence in durability and sustained performance.
Application. Specifically engineered for use as rear turn signal bulbs in Jeep Grand Cherokee models from 1999 through 2026, fitting directly into the OEM 3157 bulb socket configuration without modification.
