With non-DTRL lights you must have had a single filament bulb with two wires, a +12V and a ground which is powered by the turn signal switch and relay. With DTRL's you have a dual filament bulb and three wires, two +12V wires and a ground. One of those hots would still be powered by the turn signal switch and the other by the running lights and each going to their own filament
Right now I have the 4157 dual filaments straight from the factory. I have no DTRL.
I'm wondering if instead of running the power from the green wire from the parking light to the hot of the turn signal I would have full power AND turn signal functionality.
As of right now, I'm running power from the green wire from the parking light to the empty space on the socket. It lights up at the low end instead of high power like the DTRL.
Am I making any sense? I'm not the best at electronics but I'm trying....
