A combined radar and lighting unit includes a laser radar apparatus, a lighting device, and a controller. The laser radar apparatus is mounted to a vehicle, emits laser light toward an outside of the vehicle, and detects reflected light. The lighting device is mounted to the vehicle and emits visible light toward the outside of the vehicle. The controller controls the lighting device to cause the lighting device to alternately operate in a first emission mode to perform emission of the visible light, and in a second emission mode to stop emission of the visible light or reduce a quantity of the visible light. The controller controls the laser radar apparatus to interrupt the measurement of the distance while the lighting device is operating in the first emission mode, and executes the measurement of the distance while the lighting device is operating in the second emission mode.

In replacing stock headlights on certain trucks with new Light Emitting Diode (LED) lights, the onboard diagnostic system of the trucks do not read sufficient load resistance from the new lights and so the diagnostic system indicates that there is an issue with the lighting system and consequently limits the functionality of the lighting system. The present application seeks to provide a solution to this problem by creating a headlight adapter that integrates components for imitating the load resistance and switching functions of Original Equipment Manufacturer (OEM) truck headlights (the “Headlight Adapter ”).
