Check the fuses, if the fuse is blown you may have a short in the running light circuit.
BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
The running lights have a bad ground.
If the engine isn't running, the battery is low. If the engine is running, the alternator probably has a problem. If you are wearing dark sunglasses, remove them and the lights will get brighter. good luck!
switch dead short bad wire test wires or trace system out
short in dash light circuit, but also check tailights. Sometimes no dash lights, AND NO TAILGHTS.
