Abstract
The invention is directed to an electrical module and a method for illuminating a HID lamp on a vehicle, and in particular an off-road recreational vehicle. The electrical module and the method involve a capacitor and a voltage delay mechanism. The capacitor may be charged during the operation of the vehicle or when the operator wishes to illuminate the HID lamp. The voltage delay mechanism comprises a charge-actuated switch and a breakdown voltage means for preventing the supply of current to the HID lamp until the capacitor is charged to a voltage sufficient to illuminate the HID lamp. The voltage delay mechanism also comprises a power-actuated latch relay for maintaining the charge-actuated switch in a position that bypasses the breakdown voltage device, so that the HID lamp remains illuminated even after the voltage has decreased to the operating requirements of the HID lamp.
