There are many similar products on the market that claim to do just that. But they’d only work at night, I suspect, and even then many traffic cameras use conventional strobes rather than IR illuminators, so who knows if it would work in the right wavelength. Also, the whole retro-reflective-blind-the-camera trick works best if the light source is very close to the camera.
