Mount a photo slave multi-flash with the reflector removed from the bulb in your handle assy. This will trigger when the infrared super flash in the redlight camera triggers, and white out the tag# with overexposure in the photo. Or just run a very bright bulb with an infrared pass filter over it to keep it from being seen by the following cop.

A similar system can be used for laser doppler speed guns. I used to run a single great big offroad light, on all the time, with the infrared pass filter. This will confuse the laser detector long enough for you to spot the cop with the gun and slow down, especially if you have a laser detector. I always wondered if you could do the same with a big infrared led display on the front of the truck. Guess you'd have to know the laser gun freq, but that's just an FOI request away.
