Horns: Constant to Pulse

I'm Installing Air horns with my alarm siren, but I don't really want to have the constant sound when going off, I want it to pulse, what would I need to do that and how would I install it?

i know that dei alarms have a programmalbe setting to have a pulse horn. otherwise you have to get a light flasher to do that.

hey jaice, i personally would just add a flasher between the relay and the compressor. all you have to do is take the output from the relay, hook that up to "x" on the flasher, then run another wire from from the "L" on the flasher to the 12v input on the compressor. it should pulse nicely and flashers are extremely cheap. let me know if that helps. later

yup.. a flasher was $3 when i bought one to fix a friends parking light flash.. works great!Driving a Bagged, Caddied 02 s10
