Worked great for what I wanted. I needed to run GoPro off main battery of my bass boat. I used a 12v to 5v USB converter that is installed where the light bulb was. I cut a hole in lid and glued USB in place.
I have this mounted on my kayak and to my surprise the light is a lot brighter then I expected. Mounting the base wasn't that hard (not included ) to install. The pole slides into the base. Looks real sharp. Thank you
