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 (Blue)

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.

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

Great idea but the adhesive is not very sticky

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

Overall rating is 1 star because it does not do what is intended to do. I can barely see the reflection on my door. I tested it out during the night time and with the help of my bf. I was excited to get this because I travel to and from City alot where streets are narrow. I got this item because I would like other passing cars to see when I have my door open so they don't accidentally brake my door. The city has lighting in most places so not a huge deal but where I live there is barely any street lights on my street. Only good thing is the pieces seem to stick well and seem durable. I wish they actually worked. SAVE YOUR MONEY! NOT WORTH THE BUY!

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.

Good
