ABSTRACT:
A convienience feature is added to a DRL circuit to enable the driver to temporarily override the DRL system in situations where it is appropriate, such as when the vehicle is approaching weigh scales or entering a tunnel. The convenience feature is embodied in a convenience circuit that is interposed in the current feed path to the DRL circuit. The convenience circuit comprises a momentary switch that is actuated by the driver and a timing relay module that is responsive to the actuation of the momentary switch.
