The one on the front brake handle, I don't think it's actually broken, pretty sure it's just that little copper wedge they used to hold it in place...
Had to ride around with my brake light on all the time, bet I looked like one of those posers that come out after 5...
No garage so I guess I'll fix it in the morning...

 

Easy fix. New switch. Took me about 30 minutes. Splice, soldered, and heat shrink.

 

Did you change your bars or grips lately? If you don't wedge the lever when it goes back together the little blip on the switch gets cut right off. Ask me how I know?

 

I took it apart this morning, it was the copper wedge...
it slipped out just enough for the switch to fall into the housing, so no contact with the lever...
I changed the grips about two months ago, guess I didn't put it back in just right...

 

Same way I learned I bet....LOL
