hey, I'm a newbie on this forum but I got a quick question. I'm currently working on a small tail light project on my car. I am using a 1157 dual filament bulb, but the lower wattage filament is being used for the night time lights.
The higher wattage filament (commonly used for the brake and/or signal) is what I'm looking to work with. I have a 12VDC signal for my brake and a pulsating 12VDC signal from the blinker. I want to run both signals to the same filament so that each one alone will be able to power the bulb but when both are on at the same time, the signal will be canceled and the bulb will not light up.
in simpiler terms, I have 2 12Volt sources:
0+0=0----------0+1=1
1+1=0----------1+0=1
The components need to run on 12VDC (14V to be safe), and I will be using a relay, so the current draw will be small.
TIA
