Both of my turn signals work fine when the headlights are off, but as soon as I turn on either the parking lights or the headlights, my right turn signal, when activated, comes and stays on solid. The left side however works normal. No blinking at all. Any ideas?

bad ground at bulb socket can cause funny things. The originals ground through the housings, many people update to sockets with individual ground wires. Neill

Can anyone elaborate on an update for the bulbs? Is there a part number or website that details this swap? Are we talking about the turn signals or the headlights? Is there a way I could use a jumper wire to a good ground to troubleshoot my problem area?

using a jumper wire is a great way to test. one member ground away plastic from his sockets until he could slide a female blade connector onto the ground frame inside. my car has newer sockets that have a separate ground wire already attached. I had to slightly modify the holes in my tail lamps to make them fit properly but they always work. Good luck, Neill
