### ⭐⭐⭐ Kinda dim.
*by E***S on July 18, 2023*

Got these for the mirrors on my van. Hooked them up easy enough and checked for full 12 volts, but they're not very bright at all. I can see them fine while driving,but I don't think they'd be visible to other vehicles unless they are right on my rear bumper. Disappointed ☹️
