Overview
This harness is plug-and-play with the DV8 20-Inch Halo Elite Dual Row Light Bar with Accent Light and is designed specifically for DV8 lights equipped with accent halo features.
This 40 AMP DTP 4-Pin Halo Light Harness is designed to power a single DV8 halo-equipped light with a clean, reliable wiring solution. Built with durable 14-gauge wire, it features a 40-amp fuse and 40-amp relay to ensure consistent performance and protection. The dual round switches allow independent control of the main light and the accent halo. The halo switch cycles through OFF, WHITE, and AMBER, giving you flexible lighting options from the cab. Both switches are housed in easy-to-install round mounts for a clean interior setup.
The harness includes a 10-foot lead with a 4-pin male Deutsch connector for direct connection to compatible DV8 lights, along with a 10-foot lead for the switch. A 1-foot power and ground lead with ring terminals and an in-line fuse makes battery connection straightforward.
