Rear Lights

How do peeps…

Mate of mine has a CBR600F that he’s having a few problems with. His rear lights aren’t working but the brake lights are!! He’s checked all of the plugs etc and he’s checked the fuses but still nothing…

Does anyone have a bit of a clue what could be wrong??

Many thanks

Dont know what the rear like on this bike is but if it uses a double filament bulb like many cars, it could be that the rear light filament has blown but the brake filament is fine.

Change the bulb.

They are twin filament but there are 2 bulbs…would they both have blown at the same time??

hhhhmmmm unlikely. Pop to halfords and get some new ones, they come in pairs. Could be the circuit they run on which means if one goes the other doesn’t work either.
