is all sorted, used the ignition live off the ABS position in fusebox as this was the closest i could find, my car dont have ABS so shud be alright shouldnt it?

wire the led to live and to ignition live, wen the ignition is on, it has two lives and does not flash, when the ignition is off, it has a live and an earth and flashes, job done

An LED is a Light Emiting Diode, now its like a normal Diode but, you guessed it, it emmits light.

I diode is like a one way valve for electricity, it only lets if flow in one direction, thats why LEDs must be fitted the right way or they don't work.

With the ignition off power from the permenant live can flow the right way through the LED, but as soon as there's a current comming the other way from the ignition the LED cant let the power through which also stops power comming the other way. Look at it as a one way system in a tunnel, when traffic comes the wrong way the whole thing shuts down. Thus stopping the LED from working, and Voila, it don't flash no more :D

Quoted from Haynes Max Power Modding guide for the Vauxhall Corsa

Electricity, you need a live and an earth, or do you? I've found an interesting solution - feed one LED wire an ignition live, and the other a permanent live. This doesnt blow the LED like you'd think, but when it gets two lives it stops working - therefore, this way, when the ignition's on, the LED's don't Flash.

point is i got a hazard light switch with a LED built in out of a corsa sport from scrappy that had vaux fit alarm, n want the LED to flash

it works

Hmm, it might work. Depends on whether the ign switch on the car earths when it's off.

Maplin Electronice sell them >>>>Click here<<<< bout 1.99 I think. To get it to flash when ignition is off, wire the +ive side to a permanent live and the -ive side to the ignition +ve of your choice (eg. 1,2) so when theres a supply of 2 +ive's it wont flash, but when only the permanent it will flash

or get an alarm :D

whats the point? just get a sticker for ur window saying this car has an alarm :P

as above, where can i get 1 n how do i wire it so it flashes with ignition off?

cheers
