All 3000GT rear lights now LEDs, permanent high performance Air Filter.  Although the new electronic flasher relay now works at normal (70/min) rate, I may need to re-install some of the 2057 incandescent bulbs as the Cruise Control does not seem to be working.  I wonder if it needs some sort of resistance in the line - I might be able to get away with a few CANBUS enabled bulbs in the loop
