First Claim
Patent Images
1. A vehicle lighting control system for implementing operating condition sensitive daytime running light operation of vehicle headlamps, the vehicle lighting control system comprising:
- a plurality of exterior lamps installed on a vehicle including warning lights and the vehicle headlamps for automatic daytime running light operation;
an ignition switch;
a park brake position indication switch;
a headlamp control switch;
an engine controller for reporting engine operational status;
a warning light activation switch; and
a system controller coupled to monitor the status inputs from the ignition switch, the park brake position indication switch, the headlamp control switch and the warning light activation switch, and further coupled to the engine controller for receiving reported engine operational status, the system controller being programmed to illuminate the headlamps in daytime operational mode in response to the headlamp control switch being off and to a concurrent pre-selected state being met for at least one of;
(1) the ignition switch status, (2) the park brake position indication switch status, (3) the warning light activation switch status, and (4) the engine operational status.

Abstract
A vehicle lighting control system provides tailored implementation of daytime running light operation. Daytime running light operation is triggered in response to selected vehicle conditions, typically including, ignition key position, release of the park brake and selection of the off state for the vehicle headlamps. The occurrence of additional conditions results in cancellation or suspension of operation. Suspension follows from setting of the parking brake, typically without activation of school bus warning lights.
