Morimoto's XChange LED drivers simplify the process of achieving "daytime running light" or "switchback" functionality for any 12V accessories. Designed to replace complex wiring and 5-pin relays, these drivers offer user-friendly installation. For Daytime Running Lights, connect the DRL-output to your desired accessories and power them with a constant 12V supply. When your car starts, the DRLs activate; when headlights are on, they automatically turn off. The Switchback Function is equally straightforward: connect outputs to your white and amber angel eyes, and inputs to 12V constant and blinker circuits. The white angel eyes stay on, while the amber blinks with the turn signal. The XChange LED drivers are versatile, compatible with various 12V accessories, from angel eyes to fog lights. Quality is ensured with an attractive black aluminum housing and conformal coating for moisture protection, plus sealed 9006 Female connectors to prevent corrosion. Upgrade your lighting effortlessly with Morimoto's XChange LED drivers.
