Electrical Wizard Wanted

Help please, I have no brake light and stop indicator lamp when using the front brake ?
Both work ok when depressing the rear brake.
I have checked the front brake switch with a meter and it is working fine.
Where do I check next ?
Cheers :??

Check the brown feed wire to the front brake light switch for 12v.
If that checks out okay, then try for continuity of the blue wire between the rear brake light swith and the front brake light switch.

Thank you Big Fluff.
The brown wire came off the connecter as I pulled it from the switch.
Tested the brown wire at 12V, so ok
The Blue wire between the 2 switches also rang out ok.
Fingers crossed when I can get hold of a new connector tomorrow and re-fit all will be well ??

Brown & Blue wires touched together should light up the brake light , if they do it is the switch that is broken !

Crimped a new connector onto the positive brown wire at the switch, all now fine.
Thank you for the help.
