US Patent 7125134 Switch enabled infrared lighting system with non-IR light elimination

The present invention provides a vehicle IR lighting system where manual actuation of a single switch both activates vehicle IR lights and automatically disables all non-IR vehicle lights. The IR lighting system provides a single switch enabling an IR light source and contemporaneously disabling all non-IR light sources. The output of a manual IR light switch is connected as the control line to a relay switch. When the manual IR light switch is closed thus connecting power to the IR light, the output opens the relay connected between vehicle power and the non-IR vehicle lights thus automatically turning off power to all non-IR vehicle lights.
