The problem with lights is they only work with your foot on the brake pedal.
I like this reflector idea, been thinking about doing it as a modest strip on my PU tailgate for a while now.
I went sort of crazy with reflector tape on my flat 8x12 snowmobile/hovercraft trailer. However that did not prevent someone from side-swiping me. It was just a little bump, and I have rubber hose all along the edges so no damage.
Here is one for the record books, how unobservant and reckless do you have to be to back into a Zebra Striped Geo Tracker? The guy hit and run me, but witnesses took down the description and plate number. My wife got on their insurance companies back and they paid a fair rate to us.
