Abstract
An auxiliary lamp for a vehicle. Ordinary headlamps are restricted by law in the intensity that they direct towards oncoming drivers. This can cause inconveniently low illumination to a side of the vehicle, such as along a line 20 or 25 degrees left of center for a left-hand driver side vehicle. An auxiliary headlamp assembly is added to provide an auxiliary beam that supplements the primary beam. The auxiliary beam increases illumination along this line, yet maintains total illumination toward oncoming drivers below allowed limits.
