Alarm led's
I am trying to change the led's in my wife's car to ultra-violet led's, unfortunatly her alarm only supports 1 led. Is there a way i could wire them to constant, ign. and ground with something in-line to make them flash, and if so....what? please help!
sorry about the crappy pic!

Simple. Just wire the extra LEDs in parallel off the LED that's already there.

I know how to do it, but what i am saying is this does not work, because her alarm will only allow there to be 1 l.e.d. on the circuit. I need to find a way to wire them by themselves with a resistor and some sort of flasher relay (kind of like for a blinker) but i don't know how. I could figure it out but don't have the time. So any help???

Weird, I've never heard of an alram with a voltage sensative LED input/output. Did you try it already? If so, what happened? I have other LEDs tapped into the main on for my alarm, I even changed mine out for a hyper bright blue one, that's less wattage I think. Maybe try a lower voltage LED? Standard for alarm one is usually about 3.6v

tried it
I tried it.....like this __+__led1__-__+__led2__- but for some reason it overloaded it, I am using 3.7v ultraviolet led's and I have done it on my other car....if you know a better way, let me know!

you have them in a series confuguration, so it will halve the voltage. It might not be enough to turn either of them on. you should hook up both positives and both negatives together. That way they will get the same voltage, but draw twice the current.

Instead of how you showed it, it should look like this:+ LED1 - | ____ | + LED2 - See how both positives connect off eachother, and the same with the negatives? (ignore the line that goes left to right above "LED2")

That's odd, if you wire them in parallel, brightness shouldn't be reduced at all, or so slight you wouldn't really even notice if it were.
Are you wiring the positive of the violet LED to the positive of the existing alarm LED? If you do that, and then the negative of the violet to the negative of the existing, neither should reduce in brightness... Does the violet LED have straight wire leads coming off it, or is there a resistor of some sore attached to one of the wires of it? If so, cut it off, then it should work fine. It might help to know what alarm system you have as well.

I have an Avital alarm system, and what I did is i replaced the led that was there with a violet one and then I tried both ways described and parallel worked but was very dim, and series didn't work at all. I was just wanting to know if there is some kinda of relay I can just make my own flashing circuit thats is seperate from the alarm that loses power once ign. is +
