How to Replace a Daytime Running Light Module

daytime running lights

A dedicated daytime running light module is used in some vehicles to automatically control low beam headlight operation. The module receives input from various sensors and switches including the ambient light sensor, ignition switch, headlamp switch and parking brake switch. It then uses this information to adjust the low beam headlights as needed. A defective daytime running light module can result in low beam headlights that stay suck on, operative erratically or don’t work at all.
