Re: Flashing Dummy Alarm LED.

Hi
I believe it was a normal red LED, just flashed by the unit , maybe, but hey, that's very interesting...Can I actually fit a flashing LED to a circuit that flashes the LED itself, or would that create some problem with the electronics in the unit, or, perhaps, not even switch the circuitry within a flashing LED in time for it to work...I have to say it's intriguing
Cheers

If its a Red LED they have the lowest voltage about 1.8 v, most flashing LEDs need above 2.5v. It might work but the flashing would be all over the place, it would be OFF for the time that the unit said, then it would come on but only for the time that the LED wanted if it was longer than what the unit wanted. So you would either end up no difference at all, or with a long flash followed by a short flash.

Hi
Yes...I had an inkling that's what might happen...so i'll look out for another red one- non flashing...anyway, the alarm works, and most folk over here are petrified of right hand drive, anyway....they have trouble with a left hooker as it is :lol: :lol: :lol: :lol: :lol: :lol:
Thanks so much for your help...all is now clear
Cheers

If you really want a dummy one then look in poundland, they have them with a row of flashing led's which come on auto at dusk and go off at dawn and yes, for a pound, lol.

Hi,

Found a possible solution. Maplin do a kit for a dummy car alarm. Contains a labelled circuit board, all the bits you need with instructions. £3.99, auto senses when to come on so no external or hidden switches to worry about. Looks pretty neat.
