Abstract
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 ”).
Claims1
A headlight adapter circuit, comprising:
- a B node, an F node, and a G node;
- a first resistor coupled to the B node;
- a second resistor coupled to the B node;
- a capacitor;
- a first transistor coupled to the B node, an F node, and the capacitor;
- a third resistor coupled to the F node and the capacitor;
- a second transistor coupled to the capacitor, the first transistor, the first resistor, the second resistor, and the third resistor;
- a diode coupled to the F node and a G node;
- a fourth, a fifth, a sixth, a seventh, an eighth, and a ninth resistor coupled in parallel to the F node and the G node;
- a tenth resistor coupled to the first resistor and the second transistor;
- and
- an eleventh resistor coupled to the F node and the G node, wherein the eleventh resistor comprises a power resistor, and wherein the F node is coupled to an E node.
