I have an 03 600RR and the headlight and high beam both blew. I checked the fuse for the headlights and it's fine. I replaced just the headlight bulb and when I turned the bike on (just electrics didn't start it) it came on fine no issues. I turned it off and on a couple times and every time the light turned on. I decided to take it for a short drive in daylight to see if it would stay. Sure enough when I get back home and take a look the light is out so I pull the bulb out and it's blown again. I wasn't touching the bulb with my hands so that's not the issue either. Anyone have any ideas?
