| Bulb Location | Turn Signal Light Bulb |
Product Overview. The Diode Dynamics Red LED Bulbs (3157 series) provide a modern upgrade to traditional rear turn signals by offering instant on/off illumination and enhanced brightness. These bulbs serve as direct replacements, delivering improved visibility and a crisp, professional appearance. They are ideal for anyone looking to modernize their vehicle’s lighting with reliable, high-performance LED technology.
Construction and Appearance. These bulbs feature a robust metal heatsink for efficient heat dissipation, paired with a constant-current inductive drive circuit to ensure steady brightness while protecting against voltage fluctuations. The red emitters comply with SAE/DOT color requirements, producing a clean and compliant signal display.
Installation. Installation is straightforward with a plug-and-play design requiring no modifications to the factory bulb size. To prevent hyperflashing, an LED resistor kit is required for use in vehicles equipped with BCM/CANBUS monitoring systems; resistor installation involves simple wire tapping but is separate from the bulb installation itself.
Warranty. This product includes a three-year limited warranty, providing extended peace of mind and coverage against defects.
Application. These 3157 Red LED Bulbs are direct replacements for rear turn signal bulbs on 1999-2026 Jeep Grand Cherokee models, fitting seamlessly into the OEM socket and wiring harness without modification.
