Abstract
An apparatus for controlling an accessory that has an electrically operable device and is attachable to a vehicle. The apparatus has a switch that is mounted on the vehicle remote from the accessory and operable by an operator of the vehicle. The switch and the electrically operable device are electrically connected by controllers and a single dedicated communications wire. The apparatus has the capability of automatically determining if a DRL lighting system is present on the vehicle; and if so, accessory lights such as plow headlights are automatically illuminated to simulate the vehicle DRL lighting mode. The apparatus has the further capability of detecting an erroneous electrical operation of the electrically operable device on the accessory, for example, an excessive current.
