Ideas to address truck tail light reflection from camper?

I believe some campers may come blacked out-or maybe the owners had already done, either way its good idea.

Switch on the cab lights, I used a pilot so know when there off, use to flip down the visors. Usually a single wire feeds them. I don't have a problem with the cab light glare so much unless were in a lot of dust or fog, then it can be hard to see past. But on our standard cab thats a lot of yellow glow, makes me squint :)
