It was colored with clear blue on the part of the lens, and it was used for the front signal light when towing the tower, but solar charging can not be done within three months, lamp does not spot at all.
Although it is less than 10 minutes on one way, it is using blinking lighting everyday. I am very happy with economic efficiency with the same illuminance (personal impression) as battery type. After that it is 100 points if waterproofness and durability of LED are no problem.
I fixed it with a double-sided tape with the bracket removed to a dashboard of a tow truck and colored with a clear blue for a plastic model and used it in a blinking state as a signal light at the time of towing tower.
