Alarm!

[Essexdaz]

Hi all, I am currently fitting a alarm and I need to find how to get the hazard lights to flash when a 12v feed is put to it. Now I've tested tr back of the switch and can only get one side to light up ( not flash) and if I put a 12v feed to the flasher relay the ignition comes on!! Help!

surely you would wire it into the hazard wires to make it bypass the switch and make it live

Take care when messing with the flasher circuit, it is designed to be activated without the ignition on.

When off the contacts in the switch allow the indicators to work, you could end up with nothing working.

You could use a two pole relay, with the contacts wired to the indicators, then use an NE555 timer, then you can have it flashing at twice the speed, thus attracting more attention.

Thanks fr the replies, I have fitte a delay relay off of the interior light with a hidden switch, so I have a switched delayed 12v feed, that activate the siren and the amber lights on the roof ( I like to be different) but would like the hazards to flash too
