Not sure if anybody has shared this before but thought itd be a good idea for any other would be YALE Alarm installers.

You dont need to use the outer casing, just the electronic internals which fit nicely into the dummy siren.
Instructions come supplied but you do need a soldering iron. There are probably LED kits out there ready made, but I thought this way was fun. Nice to make my Dummy Siren look 'live'.
Shame the proper Siren doesnt have a residual LED, but I suppose that'd be a constant drain on the batteries.
The battery should last 6 months, or a year if using a D Type 1.5V battery.
