I have an answer that WORKED FOR ME and I had the SAME problem of
sometimes working, sometimes not, usually being very bright, hazards
working better than turns, etc, etc. Yesterday while at Pep Boys I
found a ELECTRONIC turn flasher! (Yes, I know Lucas didn't make it.)
Tridon, Electronic EL 12-C, works up to 10 bulbs. I plugged it in and
everything work, nice and fast, bright and clear! I can get it
inspected now!
Hope this helps,
