Brake light not working

[declan]

I've wired a new tail light up and just installed a new rear brake light switch and it doesn't get brighter at all when the switch is activated is it possible I've wired the tail light up wrong?

@declan If it's an LED light then you will have some problems. LED's don't work with the standard set-up, I stuck with regular bulbs in the end as I could not suss it all out. There is a thread with someone finding a solution to this problem on here somewhere???

@CYBER-NINJA the tail light does work perfect and bright just not when you press the brake I've just ordered some indicators with built in brake lights so need to sort it out

my bike is running all leds apart from the headlight and they all working ok i have got a led headlight to fit but not had a chance to try it out yet but will update the thread when i found the right quality bulb

I run surface mounted diodes for my rear light no problems.

There is no circuitry involved with the rear lights, it's simply a switch hooked up to the 12v rail on the bike. So test for conitunity between these two lines and you should be able to figure it out.
