Default Bulb blowing
Last couple of days my dipped headlight bulb on my 03 Cbr600rr has blown 3 times!!
it comes on with ignition turned on and also after a ride,but the next day I turn it on it’s blown again and also once during a ride out.
anything I should be checking,I’ve not touched the glass at all while fitting the bulb
thanks

Check you charging system output voltage. I would bet it's too high due to a faulty regulator.

I'd check it at a range of rpms to see how high it gets.

You have it on the right scale, and that is way too high. If you keep running it, blown bulbs will be the least of your problems.

Get a new regulator a retest.
