About a month ago my significant other picked up a used 05 600RR. After about a week we were heading up the highway and I checked to see if she was behind me and her headlights were off. A looked again a short time later and then they were working again. This hasn't happened since until tonight. We stopped and they went out and haven't come on since. I found the fuse and it was still good. I tested the the socket and the bulbs are not getting any current at all. Tomorrow I am going to start pulling plastic and tracing and checking wires. This is my first time working on a 600RR. Any advise or warnings would be greatly appreciated.
