1988-2004 Corvette C4-C5 Headlight Actuator Control Module Electric Relay 16510537

1988-2004 C4-C5 Headlight Actuator Control Module Electric Relay 16510537 - OEM Number(s) (16510537)

Restore reliable headlight operation with the correct GM actuator control module.

Beginning in 1988, GM replaced the unreliable three-relay system with a single electronic headlight actuator control module to govern pop-up headlight movement. Mounted on the left-hand fenderwell, this module manages the rotation and stop points of your headlight motors. If your headlights refuse to rise or close properly, a failed module is often the cause. This direct GM-style replacement restores smooth, dependable operation for your C4 or C5 Corvette and ensures your pop-up headlights work exactly as intended.
