I have a 99 CBR 600 F4 and I was out riding last night and the headlight stoped working. The bike has not been dropped, the bulb is good, and the fuse isn´t blown. What else could cause it not to work? The high beam indicator doesn´t even come on when I flip the switch. but my front directionals still work fine. I tried plugging in another bulb and it didn´t work.
