• Abstract:
  This report describes the development and testing of a draft test procedure confirming the performance of vehicle automatic activation systems for lower beam headlamps (a.k.a. low-beam headlights) that turn the lamps on and off based on ambient light level. A valid laboratory-based method was developed for simulating ambient sunlight coming from a realistic direction and measuring that ambient illumination at a vehicle’s exterior windshield surface.
