RV security project

[Britcanuck]

I am trying to build an RV theft deterrent for my motorhome. I don't want a system that alerts my smart phone to a break in. I am a believer in scaring the bad guys away before they cause damage. I envisage a wireless PIR that I can fix to the top of the coach windshield pointing 45 degrees down. Inside, and pointing out through the windshield is an emergeny vehicle LED flashing light red & blue. This light is powered by a 12 volt dash outlet. I need some kind of receiver /switch that can receive the motion signal and open the switch to turn on the LED light. This last component is the difficult one to find. Any ideas?

I think you don't really need mysensors for that and I believe pir sensor is not going to work well behind a glass.
