So I recently purchased switchback signal lights for my 2006 f150 and they were great for a while, but now my dashboard right turn signal indicator light is on. Its not fully lit but it is dim. Same with my signal light, it stays a dim yellow all the time when the lights are on when the should be white. When I signal the turn indicator fully lights up and blinks light normal, same goes to the signal bulb it signals like normal fully yellow. But goes back to a dim yellow when signals are off. My left turn signal works like it should. Anyone know whats going on?

All over the truck, need a shop manual to find them all.
