Here is a strange one not sure if it’s normal but front light bulb blew while out due to age this in turn made the back light realllly bright as rpm climbed and Fryed that bulb is it the norm that both bulbs need to work or it dumps the extra power in nearist bulb that’s on

It's possible that your rectifier/regulator has gone ...you'll find it under your seat & mounted to the frame ....( about the size of a box of matches with fins on it ) .... Check & clean the wires that go into it & spray a Lille WD40 around the terminals .... You may be able to check it's working properly with a multimeter .... They aren't expensive to replace if it's gone.

Which model is it??

All stock parts?

Yes, check your connections to the Regulator, if its bad, or not connected, you can blow bulbs at high rpm.
