Product Overview. The Diode Dynamics Red LED Bulbs; 3157 XP80 enhance the turn signal lighting on your Jeep Grand Cherokee with a modern instant on/off LED effect. Designed as a direct replacement for the OE 3157 rear turn signal bulbs, these LEDs add a contemporary look while maintaining proper red signaling compliance. They are engineered to provide consistent performance and reliable durability for extended use.
Construction and Appearance. These bulbs feature sixteen high-power 5W LEDs arranged omnidirectionally, mounted on a metal heatsink for efficient thermal management. The body incorporates an inductive constant-current driver circuit that offers stable brightness and protects against voltage spikes. Finished in robust materials to withstand automotive conditions, the bulbs maintain a clean and uniform red output through an appropriate lens color.
Installation. Installation is a straightforward plug-and-play process requiring no modifications or drilling. The OEM-sized connector fits directly into the factory socket. Installation of LED load resistors is necessary to maintain proper flash rate and avoid hyperflashing.
Warranty. These LEDs come with a 3-year replacement limited warranty providing peace of mind for long-term performance.
Application. Designed specifically to fit the rear turn signal bulb socket size 3157 on Jeep Grand Cherokee models from 1999 through 2026, enabling a precise, model-specific upgrade without fitment concerns.
