This is sold a s replacement for a car dome light but it is useful for many other things. It comes with three different adapters to replace standard car bulbs. These can be cut down to adapt it to other uses. It comes with a foam adhesive tape mounting on the back of the unit. I have used two units to build a work light for my drill press. It puts out a bright white light and helps me to work safely. It comes in an anti static zip lock bag. I recycle the bags for use as electronic component storage. It is made in other colors although I don't Gear Best carries the other colors. Too bad as they would make great stop light bulbs.
