[QUOTE="torch, post: 1448331, member: 1295"] So you want to suppress the marker light function while the signal on that side is active? The trick is to keep it off for the 1 to 2 seconds that the turn signal is dark. With an incandescent bulb (or separate LED) some sort of timer circuit, such as a 555 timer controlling a NC relay could be started each time the turn indicator bulb gets power, opening the relay contacts. Timer is reset each time the bulb starts a flash so the marker light stays off until the turn signal has been inactive for the timer duration. A 556 timer is dual 555s so could handle both sides in one chip. I did something similar in code for the flash function of the project above. If I relied solely on the turn signal power, then it would not function when brakes were applied (ie it would alternate between turn and brake -- no effective difference. I could easily change the value between flashes to 0 to suppress the tail light function on that side while the turn signal is active. I thought about it, but having the tail remain active between flashes seemed to make it more obvious when the brake was applied. [/QUOTE]
