You tried the front and rear brake ? Could be bulb

Is it factory or after market ?

If it's under warranty take it in.

Check your rear pressure switch. Mine (Gen1) was doing same thing. I cleaned the connector and fooled with the wires (thought it was a loose/bad wire) And it seemed to fix it. I still check it periodically to make sure still working. So far so good. Hope it helps man

They are led lights, I had the same trouble seems the circuit to the brakes to make them light up sorted out and I had to replace the tail light. You can open up the light by puting it in the oven to open the seal then replace the circuit but I took the cheaper easier option by buying on from Hong Kong on ebay.

factory

where is the switch

 

[dadofthree]

One switch will be up next to the front brake lever the other switch will be behind the rear set near the rear brake reservoir. First I've heard of the circuit board issue. Good to know.

This could be your best option.

Have you made any mods that would've effected the brakes (e.g. new levers)?

You said the brake light is on (one might assume you meant the tail/parking light), but could it be that the brake light is actually on due to a stuck switch?

My guess would be a faulty switch or, as aussie said, faulty circuit in the tail light assembly.
