This wire harness offers true plug-and-play compatibility with the DV8 7-Inch Halo Elite Round Light with Accent Halo and the DV8 20-Inch Halo Elite Single Row Light Bar with Accent Light.

Power your DV8 halo lighting using the 40 AMP DT 4-PinHalo Light Harness. Built with durable 14-gauge wiring, this harness is designed to deliver consistent, reliable power. A dual-switch system allows independent control of both the primary light and the accent halo. The round, easy-to-install switches let you toggle the halo between OFF, WHITE, or AMBER, giving you flexible lighting options to match driving conditions or styling preferences.

The harness utilizes a 40-amp fuse paired with a 40-amp relay to help protect your electrical system while ensuring stable power delivery. A 10-foot wire lead with a 4-pin male Deutsch connector provides a secure connection, while the 8-foot lead routes cleanly to the switch. One-foot power and ground leads include an in-line fuse and ring terminals for straightforward battery hookup.
