[Healeys] turn signals and tail lights

[linwood rose]

Earlier in my restoration I thought I had sorted this problem out,  
but tonight it has come back to haunt me again. I have just installed  
my newly painted rear shroud and I was installing and hooking up the  
tail lights. By the way, getting those chrome trim rings to fit  
inside the rubber housing was a real pain!

Here is the situation: All components are new( flasher canister,  
relay (electronic variety, not the original coils), lights and  
bulbs). If lights are off and turn signal is activated, both left and  
right tail lights operate perfectly. If I turn the driving lights on,  
the turn signal in both lights is barely perceptible. I have  
carefully checked my ground connections throughout the car, and  
removed fresh paint where ground connections are to be made, but it  
doesn't seem to have affected this issue. If a faulty ground was the  
problem wouldn't the flashing signals have failed when the running  
lights were off also?

I would appreciate any suggestions that I might try to solve this  
problem.

Thanks.
