Use them as oversized cargo lights. The magnets are incredibly strong and do not cause any problems when charging on round tubes. The only problem is the brightness. When I see them in the mirrors of my caravan, they blind me, they are insanely bright! Illuminates the cargo, the road, the curb, the trees, everything. DOT assured me of their quality when I worked with them as pilots. I removed the star because the light is directional and not coming from above. Otherwise they are almost perfect.
