Just wondering what y'all think of this... it could easily be incorporated into any jammer with both front and rear heads.
The concept is simple. When the front heads are hit with laser, the rear heads fire as well to provide a laser warning to RD users behind the car with the jammer/repeater. Perhaps some jammers work this way already, but AFAIK most will fire the front and rear heads independently. A simple firmware modification would do the trick.
For those who don't have rear jammer heads, perhaps an LED IR emitter placed in the back window could provide the same feature. Tie it into the jammer's alert output or radio mute and then your jammer could provide a service to those behind you who have RDs.
