Hey all first time in a forum, first time posting. The problem im having on my 05 F250 is I bought some LED lights and resistors from a local part store put everything in turned on lights and everything works great. The issur im having is whrn the lights are off and I turn my signals on everything starts blinking even my dash lights. I've been online and cant seem to fing anything out sbout the dash lights. (Huh) so here I am to see if someone can help me out.

 

Sounds like you may have lost a ground connection in the process.

 

I was going to do the LED route myself wondering what it could be too?

 

Cheap lights? Check the wires and connectors and make sure there is no pinched or broken wires on the sockets. Keep us updated.
