2004 Ram . The LAMP OUT light is on in the dash. all lights work except RR turn sig . When the right turn sig is applied , the relay clicks real fast , and the rear sig doesnt work . Front sig works .

Its NOT the ts bulb , ive tried 3 . and the weird part is this = with the whole tail light assembly removed and unplugged , I tested voltage at the plug from the truck harness.

It should flash from 0 to 12v or so consistently yes ?? It just sits there at a solid 8V on the ts terminal. Any ideas ??
