An innovative "U" bracket allows you to mount it on the lip of your hood or trunk, a place motorists might not expect to see a light. A screw mount allows permanent placement. The tough automotive-grade adhesive mount for allows temporary placement. The extremely thin size and positioning options of these lights allow them to almost disappear until illuminated!
