4PCS Car Door Open Warning Reflective Stickers, Night Visibility Auto Safety Prompt Decals, 3.6 x 0.9 Inch Anti-Collision Protective Strip, Car Accessories Universal for Truck, SUV, Van (Yellow)

These reflective pieces are great. As you can see in photos I use them in the door jams for oncoming vehicles who may not otherwise see an open or opening car door. The reflectors adhere strongly and have no issues with them since the application. Bright vibrant blue you can’t miss. These are a good fit for adding safety to your vehicle.

Bonitos pero no alumbran como la imagen

Looks nice on vehicle and easy to install. Bright and reflective at night time.

Total just. Falls off. Even when cleaned good. Do not buy

Sticker need to be larger. While it is reflective, it's just a curious fluorescent green "dot" from a distance. Still, it does look nice and it's better than nothing to help catch the other driver's attention.

I liked to put them on the door so it lights up more.

Good product. Met my expectations. Would recommend to a friend.

This product provides a bit of extra safety for very low cost and very little effort. I had such reflectors on doors of a car I sold. And I found I missed them on my new car — whenever I opened my car door on a dark street at night, I wondered if cars coming from behind would notice.
