Tinman58's unfortunate experience motivated me to delve into a subject I've been pondering for a while.
Situation: TR3A with corner brake/tail and inner turn sig lights.
Desire: to turn both bright filaments on each side into brake/turn signals.
Problem: making the turn and brake systems interact properly, so that the turn sig flashes whether-or-not the brake light is on.
Internet research has turned up the information that the many cars that perform this trick use different switching at the turn sig switch than we do. They have more wires running to/from the switch, and more stuff inside the switch than we do.
Further internet research yielded the schematic, below, obtained from an old-car forum, utilizing two DPDT relays to achieve the desired result. Looks to me as though it should work.
Any comments from the more electrically savvy amongst us? Is there an easier way? If not, further internet research has NOT yielded a wide variety of good looking options for adequately weatherproof automotive style 12V DPDT relays. Any hints on that one? (I do already know that I can wire-up 4 easily available SPDT relays to perform the same function.)
