If your parking lights are on and your left brake light doesn't work, the brake may have burnt out. You might also have a wiring problem.

BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
fuse, bulbs
Maybe the problem lies in the switch that operates the "brake" light when the parking brake is applied. The DRL do not light up until the parking brake is released. I know that if my parking brake pedal is down so much as one "click" of the ratchet mechanism, the DRL do not illuminate.
If the cable is broken and parking/emergency brake is still ON, then they are rusted in place ! - Your emergency brake system needs urgent work.
