A vehicle light system circuit includes a PROFET to automatically detect the presence of a faulty light source and switch to an unaffected light source. The system also adjusts the brightness of the unaffected light source by adjusting a PWM signal applied thereto to approximate the brightness of the unaffected light source.

Vehicle light system circuit which automatically compensates for a light source failure

A vehicle driver module 10 with circuit 12 for receiving a first signal from a vehicle's controller and providing a second signal responsive thereto. The circuit 12 being placed on a substrate 14 constructed as a heat sink and preferably formed into a U-shaped configuration. A plurality of terminals 16 are attached to the substrate 14 with collars 18 made of an insulative material and having posts 20 constructed to fit within openings 50 of the substrate 14 be fastened thereto and retain the terminals 16 therein. Each of the terminals 16 include a prong 24 projecting out one side of the collar 18 and a clasp 26 out the opposite side of the collar 18. Each clasp 26 is constructed to provide a snap electrical contact at a predetermined location on the circuit on the substrate. The prongs 24 are selectively spaced so as to be received in and mesh with the standard vehicle relay junction block. The vehicle driver module 10 is a solid state, high-speed, high-power switch particularly suited for vehicle headlamps for daytime running lamp operation.
