Review on Enhance Safety with Swpeet 20Pcs Universal Red + White Stick-on Car Reflector Sticker- Ideal for Most Cars! by Johnny Chambers

These reflectors were screwed to a wooden fence without adhesive backing as the fence posts were not very flat. Instead of painted lines, reflectors are used to mark parking spots in a gravel parking lot. The reflectors are clearly visible, but the surface of the plastic used is soft and easily damaged. Overall, they solved this problem at an affordable price.
