I have a short or bad switch that I am hoping someone else has run into. My left turn signal now glows at dash and front and back when I turn on my parking lights or head lights - when I turn them off, they operate correctly. Sometimes really bright and other times dimmer.

Anyone have any ideas what might be causing it?

My turn signals on my '72 started doing some real crazy stuff like that once. Turns out that the solder contacts on one of the bulbs had mushroomed to the point that they were shorted together. It caused me weeks of frustration because I kept trying to troubleshoot the car, which was fine once the bulb was removed to take voltage readings!
