When I tried these reflectors on my commercial vehicle, they greatly improved my visibility on the road at night. They were easy to stick on my truck's surface and have high-quality adhesive that withstands weather elements. The reflective materials are bright and catch the attention of other drivers on the road. My only concern was they were a bit smaller than I imagined, but they still get the job done. Overall, these reflectors are a cost-effective and efficient solution to enhance safety while driving at night.
