wiring strobe lights and LED's to alarm

Fireman1321, Check out the relay section of 12volt.com, it shows how to build a relay to change momentary to constant output. The output time depends on the size of the capacitor. The LED's can be put in series if you are talking about the DEI alarm LED's, I've actually have four in my vehicle, including one varad tri-color LED module that is activated by the starter-kill output. Good luck on the firefighter bid, I am a professional airport firefighter for seven years now. LJ Wolf Co. LJ Wolf Co

I think the easiest way to go would be to add the strobes to the siren output since it's already a const output. You would have to add relays but no big problem. You could also series the LED's but I usu buy 12volt LED's from radioshack and wire in on a relay.
