I drive a small car, I absolutely hate it when pavement princesses come up from behind and blind me. In general I want to give the cops as little reason to issue tickets as possible. Retroreflectors are why we can see signs from a distance when it's pitch black, so it's a good option that doesn't technically break any laws even if the law is basically completely unenforced
My two cars are a Miata and a Jeep. You better believe when I got the Jeep lifted I was extra careful about making sure the lights were aimed properly. That plus making sure I never follow too closely and hopefully I’m not doing the same thing to other people that everyone does to me in the Miata.
Yeah cops don't even pull people over with unaimed blue HIDs in halogen housings even though they can be spotted from miles away. The dispatcher also just wouldn't believe you if you reported someone for having a James Bond gadget on their car.
Can confirm. Inspired by this comic, I installed such a light bar in my car. Of course the very first tailgater I used it on so happened to be a cop. He just laughed when I explained why I did what I did, and then told me to never use it again. That was it. No ticket, didn't force me to disable it in front of him. I just promised him "never again" and was sent on my way.
The plates use retro-reflectors. Does not help much.
You see, if you have good/accurate retro-reflector, it reflects back to the light source. You need scattered reflector, but then, it is not as bright as to make incontinence for whoever uses high beams.
It would be the size of smallish traffic sign. (They have reflective paint too). Still nothing special. I think it is better to install slightly convex mirror so that it directs the light into the offending driver eyes.
