Thanks Abe,
I think the 56-7 T-Bird/Lincoln turn signal switch is cleaner and easier. No relays, no extra switches, no diodes, etc. It uses the existing rear turn signal bulbs as extra brake lights with **NO** visible external modifications!
Compare the switch in the photo with your stock 41-48 Lincoln turn signal switch. It's a direct, bolt-in replacement with the necessary additional wiring!
This switch is available (NEW) from T-Bird parts dealers for about $90
