tail light problems

[ron755]

On my 2003 Arctic Cat 250,   with the headlights on, I have no tail light /no stop light.

with headlights off, I have brake lights, no tail lights. Where should I start looking for my problem?

double checked

Start by  checking the  ground wires  for the tail  lights. I would suspect  there is corrosion preventing a proper ground. The  tail  lights  are feeding  back through the common power  wire connecting headlight and tail light .. When  headlights are on  that  circuit is powered so it cannot  act as a  ground.

Thanks for the help. My tail light was  rusted  inside,and was not getting a ground. Rusted so bad, I'm going to have to replace the whole thing. Thanks again.
