I want my alarm to drive a total of 4 LED's. The manufacturer said I could only run two without problems. Any electronics guys know how to do this?

use a relay, so that you can power all 4, but not have the added power go back into the alram unit.. The saint

You mean a Bosch style relay? Wouldn't the current required to drive the relay be more than if I just ran the 4 LEDs in parallel? Maybe you mean a smaller relay?

yes..that is what I was thinking..the led's might fry with 12volt..maybe introduce LED to resistor (s) I know you can wire them in series..I just did 2 and it works fine.

The DEI629R would be the easiest way to go. I had a couple of these modules on my last car and they are easy to install, plus I had them on the exterior (drilled into head & tail lights) and had no problems. About $20.00 on e-bay.

Find out what voltage the L.E.D's are and then use a small relay to power them. Just out of curiosity why are you powering so many leds? ------------- ~The Rookie~

Don't let the smoke out of your equiptment..it doesn't go back in.

I'm concerned about the battery loss and constant "clicking" from the relay just for LEDs. If I run the relay trigger to a constant-when-armed lead from the alarm, is there a way to make the led's flash?
I already have two LED's integrated into a very expensive clock/information center and I'm not removing them. Then I saw someone with LED's in the headlight and it looked pretty cool. I was just entertaining the thought, but I know after I drill into the headlight housing it's past the point of no return.

I could, but I'm meticulous and they probably wouldn't flash at the same rate.
