Hi. Have a 2002 f150 xlt. The other night I got in, turned headlights on, and noticed both my turn signal indicators are on , on my dash, both left and right turn signals flash fast, all four work, however my Right headlight is dim also., unplugged my right head light, but the indicators on dash both still on. Any suggestions or advise would be helpfull . Thanks

 

After process of ilimination, I tracked it down to a loose ground wire on my right headlight.
