[Healeys] Light Issue

[rkeysor]

I find my left front turn signal light flashing more rapidly and dimly than
the opposite number on the right front on my BN7.  Conversely, the parking
light bulb on the left is brighter than that on the right. I've tried
switching bulbs without success.  I  get a bright light on the wrong filament
on the right side if I push the bulb into the socket with the incorrect
orientation. Whether germane or not, I recently replaced the wire from the
flasher relay to the left front turn light flasher after it stopped working.
 That restored the bulb's flash function, but it's  rapid and dim, as
described.  I also removed all of the connections from the flasher unit some
months back, but I believe I reinstalled the wires correctly. This is the
second time I have replaced wires to what I'll call parking lights, the
earlier one to the left rear. In each case I believe the lighst previously
worked fine.  Puzzling.
