Designed for a close, reliable fit, the GPM Center Brake Light TRX4ZSP61 uses durable ABS to provide a stable mounting surface and a smooth finish on the rear of the Traxxas TRX-4 Mercedes-Benz G 500. The unit accepts the supplied LED and cord assembly to produce consistent brake illumination. Installation calls for controlled trimming of the shell and correct seating of the bulbs to maintain solid contact and dependable operation.
