Swpeet 20Pcs Universal Red Plastic Rectangular Stick-on Car Reflector Sticker, Door Reflectors Interior Red Compatible Warning Plate Adhesive Reflector for Most Car

I used these to mark a narrow wooden bridge. I didnt have enough, so I used a few round ones also. The round ones are quite a bit brighter, so these are definitely not as good as they could have been. But they definitely served their purpose for what I used it for. I used the screw holes for mounting.

Terrible quality! Non-reflective! Cheap plastic! Shame, really!

Very reflective. Especially the white reflectors.

Good value and well made (for being cheap plastic).

Installed on my fence posts. Good fit. Nice qualify. Very satisfied. Great price.

They worked great. Make sure you’re OK with your position before applying. Solid adhesion and won’t be easy to move.

Great product. Not only is the adhesive really sticky but you can also use screws to attach.

The adhesive is remarkably adherent.

They stick on perfectly, all weather

I used these on my front gate and are working great! Highly visible, very easy peel and stick and strong! I love these! Exactly what we expected!
