Cbr125r 2007 rear light fault
 

Hi I'm new to riding these and have a problem with the rear tail light. To start with when the brake is pulled in the brake light comes on but the light so that I can be seen at night doesn't come on at all any suggestions?

Check the bulb....

Hi already done that there's nothing wrong with the bulb I may still change it as it could be that simple but if it's not what might it be?

Might be a lot of things. The bulb is a dual filament bulb. Replace it with a known good one and see what happens. If that doesn't work, you will need to trace the circuit for power loss.
