Put a new bulb in.
Caterpillar Cowboy Thanks this. -
Have you checked for power at the plug that goes into your brake light at the rear of your trailer?
Caterpillar Cowboy Thanks this. -
If you have power to the light, either your light is broke or your light needs a proper ground connection.

Best way I've found is to start at the bulb and trace it back to the power source. Many times it turns out to be a bad ground connection...
