Brake light not functioning

Hi all,

I cant get my tail light lighted up when braking, both front and rear. The rear brake was ok 2 days ago, but not now. I have checked the fuse, but it seems ok. Took out the tail and nothing seemed disconnected. The front was a known problem due to some setting required on my rizoma lever, but the rear has been working well. Any help gentlemen?

 

Tail light is LED. Maybe a multi-meter shoukd be able to tell. Thanks Richard.

 

Lost hope. I guess it's time for a garage guy to check the problem.
