That's the only thing i can think of. I believe its a hydraulic pressure switch, and it must be actibg up in the cold..... but why?
brake fluid contracts in the cold, so that's not it. Unless its water-logged and freezing..... You do change/flush your brake fluid every 2-3 years, right?

They definitely weren't on the previous evenings when I parked the car. Depressing and releasing the brake pedal turned them off. Figured that the problem may have been caused by the particularly cold weather we were having - and the problem did disappear last week when things warmed up. Unfortunately it reappeared this morning and it wasn't particularly cold.
