I just added a car alarm to my car and I mounted 2 blue LEDs on my front pillars that flash when it's active. I was hoping to tap off of the existing LED, but there's just not enough current to power all 3. I decided to jus tap a 12V source and make my own LM3909 or 555 flasher.
I tried searching for some schematics for this, but I only came up with 1.5V and 5V circuits. I need something that can work on a 12-14V system. Both LEDs will run around 20mA and I want both to flash at the same time (prolly run in series...BTW, each one is on the opposite side of my car).
Thanks.
