Yeah I hope that is the cause. Low beam went last night on the front - have had the bike 6 months now, no idea when/if the front bulb got replaced before that. Considering the rear light goes all the time, and it's always just the tail light and the brake light keeps working, is it possible the low beam going now could indicate a wiring issue? Vibration is a lot easier! LED bulb shouldn't blow out from that, so it is a simple solution. My road home is a VERY bumpy country lane. Hi, you might want to check the voltage across the lights with the engine running there might be an excessive voltage issue there. Make sure the battery connections are tight and the battery is in good condition. A bad connection or a duff battery with upset the voltage regulator and cause all sorts of problems.
