I recently had problems with my headlights going out repeatedly, after replacing the harness with the newer style heavy duty harness anticipating installing the projection style lamps. After buying replacement relays twice from the original vendor, I had a visit with a true parts man who understood how to look something up in the book vs. relying on what he was told by the computer, and buying a pair of B/W #4136 relays.Problem solved. Cost more, but warrantied for life. What I learned is good ain't cheap and cheap ain't good. Driving blind is the pits.
