Description
Stock Harley-Davidson passing lamp circuits shut down when you switch to high beam—a safety liability that Custom Dynamics solves with this purpose-built control harness. By allowing your passing lamps to remain illuminated independently of your headlamp mode, you maintain maximum visibility during high-beam operation, giving you better sight lines and making your machine more visible to other riders and drivers. This is a simple bolt-on upgrade that eliminates a design flaw and enhances your riding safety without modification to your bike’s factory wiring.
