I'm trying to add DRL to an old car. The idea is to have DRL on when ACC is on. When the head light is on, DRL would be off.
I've been learning about p-mosfet on this board and come up with the follow circuitry (modified from other designs in this forum):
Questions: why do I need R1? if so, is 1K enough? Is there something else I miss?
Appreciate all the input.
BTW, the DRL spec is 12V, 8W.
