Nice, 10Wheels!

The beauty of hi-vis reflective is that it's always hi-vis, day and night, whereas lights have to be not just on, but extremely bright for daytime effectiveness.

I'm compelled to put some hi-vis reflective tape on the back of my trailers...

Here's one of the setups I was talking about earlier, and while you can see there's the belt line silver reflective tape, there's plenty of space for some hi-vis yellow or orange striping on the back as well. I've just got the lights in this video in a random slow flash mode, but they're fun because you can fix the colors solid or mixed, have them chase across the back, or flash in various phases.
