filters – Eliminate reflectivity towards oncoming traffic headlights

I have a couple of adapted commercial CCTV housings mounted on my car roof to do casual facial recognition tracking and license plate tracking. The issue is that the glass on the front of the housings seems to sometimes reflect the headlights if traffic approaching my car at night and there’s a very slightly possibility that’s not up to state code, or even if it is, it’s kind of a dick move.

I’m not a photography aficionado and this might not be the correct place to ask, but is there some kind of filter I can put in front of the housings that will dampen or eliminate this glare?

This is a very similar model before being adapted for use on an SUV.
