HD Relay: Light Bar

The Morimoto HD LED Light Bar Wiring Harness is the premium solution for powering aftermarket LED light bars and auxiliary LED pods safely and reliably. Designed to supply clean, consistent battery voltage directly to your lighting system, this heavy-duty relay harness eliminates voltage loss while protecting your vehicle's factory wiring.
