hey everyone...

this is my first post here in the forum. i purchased 2 blue LEDs that i am placing on each front door (by the window controls). i would like to have them light up when my car alarm is armed (ON). i cut off the little red LED that came with my PolarStart alarm/starter. i hooked up the red wire of the new LEDs to a constant power and the black wire i hooked up to the accessory wire that went to the original red LED that i cut off.

(Varad LED instructions)

the new LEDs light up fine when i turn on the alarm. but when it's off i can see some faint blue flckering coming from them. i do not know where this residual activity is coming from.

should i try to use another accessory wire? which one should i use on the alarm? i know that i can just hook them up throught the ignition and have the LED's go on when the car is off... but i'd specifically like the LEDs to light up when the alarm is actually armed. there is the yellow wire coming from the LED that i can also use. here is a wiring schematic of my alarm. i circled the wires that i'm currently using. i know that i'm not hooking this up right. some please edjumakate me. =)

Try cutting the ground off of that led accessory wire, and try connecting it to the sarter kill output wire(WHITE/ yellow accoring to your diagram) But you will need a 1amp diode to do this. Tap into this wire with the ground from your leds and install the diode between this point and the starter kill relay. Make sure that the band side of the diode faces the end of the wire towards the alarm and not the side with the starter kill relay.

well... i decided to just wire them in series using the basic POWER/GROUND/IGNITTION hook up that turns them on then i start the car. the problem that i'm having now is that the LED's don't fully light up right away. it sort of "st-st-stutters" before giving a full glow. is it the way i wired it up? i checked all the connections and they are all good. i'm going off my wires on the back of my deck. this happens when the radio is on or off, doesn't matter.

help?

thanks.

Are these 12v blinking LEDs?
