My turn signals work fine until I turn on the headlights. They even work with the running lights on, but when I turn on the headlights no signals. I can't seem to find the problem. Any ideas?

Jeff, Those are on 2 completely different circuits. Check your ground. Most probably need it anyway. If you are new to Triumphs and British cars,grounds are notorious for being a problem. Do you have a schematic??
 
I agree, almost certainly a ground problem.

One possibility, tho not by any means the only one, is the bulb holders at the rear. The original holders were a lousy design : the ground path is through two dissimilar metals held in contact only by the plastic shell. When the shell distorts with time, the brass finger is no longer in good contact with the steel spring and the result is no ground connection.

Current replacement bulb holders (from the usual suspects) are redesigned with a separate ground tab. Requires a little extra work to install (you have to fabricate the ground wire), but solves the problem forever.
