Diode Dynamics Red LED Bulbs; 3157 XP80 (98-23 Ranger)Find parts that fit my vehicle

High-Performance LED Turn Signal Replacement. The Diode Dynamics Red LED Bulbs; 3157 XP80 serve as a direct replacement for factory rear turn signal bulbs on Jeep Grand Cherokee models from 1999 through 2026. Designed to provide instant on-off illumination, these LEDs modernize your vehicle's signaling by delivering brighter, faster, and more visible flashing compared to traditional incandescent bulbs. They enhance safety and style by meeting stringent red color requirements and ensuring correct signal brightness.

Construction and Appearance. These bulbs feature sixteen high-power 5-watt LEDs mounted omnidirectionally on a metal heatsink, providing excellent thermal management and durability. The bulbs incorporate an inductive constant-current driver circuit with transient voltage suppression, which protects against electrical spikes and prolongs lifespan. The red LED emitter color meets SAE/DOT red requirements for rear turn signals, ensuring clean and consistent light output.

Installation. Installation of these LED bulbs is plug-and-play with the factory 3157 socket and requires no vehicle modification, making the upgrade straightforward and quick. However, to ensure proper function and prevent hyper-flashing or bulb-out warnings, the installation of LED load resistors (not included) is required due to the vehicle’s BCM-controlled system and PWM operation. This requires tapping into the vehicle’s power and ground wires.

Warranty and Application. These LED bulbs come with a three-year limited replacement warranty, reflecting confidence in their quality and durability. They are specifically designed for the rear turn signal sockets sized 3157 in Jeep Grand Cherokee models manufactured from 1999 to 2026.
