shokjok better than nothing i have an alarm hense the ultra bright blue that aftermarket alarms have, red is stock no alarm. plus the leds light up the whole light housing at night looks cool.
"OK, so you have an existing LED that is part of the existing alarm system and want four additional LEDs to flash and mimic what you already have?"
Exactly.
"Another option might be to have the signal driving the existing LED drive a transistor slaved to it and the transistor drive the remaining LEDs."
Thats what i was thinking, what about a darlington pair? Any suggestions on transistors, I suspect the alarm output is 20mA at around 3V.
