Diode Dynamics DRL Harness

 

Diode Dynamics DRL Harness gives customers adding or refining daytime running light behavior on compatible Diode Dynamics lighting upgrades a vehicle-matched wiring accessory for DRL functionality in supported Ford Mustang and Subaru WRX applications. It is made for customers who want clean daytime running light operation from a harness designed around the matching lighting product without turning a lighting upgrade into guesswork.

The harness routes and controls power so compatible lighting upgrades can function as daytime running lights. Instead of leaving customers to work around lighting upgrades that need a matched harness before DRL behavior can work correctly, it provides application-specific harness versions for supported sequential turn signal and C-Light systems for a cleaner result when customers are completing a Diode Dynamics lighting upgrade and want the added DRL behavior the matching harness enables.

The family includes a Ford Mustang sequential LED turn signal DRL harness and a Subaru WRX C-Light DRL harness. The Mustang version is supplied as a pair, while the WRX C-Light version uses a module to control both sides of the vehicle. Customers can match the accessory to the light, housing, circuit, connector, or vehicle application before installation begins.

Customers should match the harness version to the vehicle and the specific Diode Dynamics lighting product being installed. Fitment is application-specific, covering supported Ford Mustang sequential LED turn signal and Subaru WRX C-Light installations. The right version helps the finished upgrade stay cleaner, easier to service, and better matched to the job. Careful preparation, secure connections, and clean placement help the accessory perform as intended after the installation is complete.

Whether customers are upgrading for daytime running light function, signal upgrade completion, or vehicle-specific lighting refinement, the Diode Dynamics DRL Harness delivers the matched wiring support needed for compatible DRL upgrades. Now Available at LEER!
