Here are 2 brand new LED Motion Sensor lights for about $12 each, including batteries. The top brown light only has one super bright LED - but it's much brighter then the white light with 3 adjustable LEDs. The brown light has what looks like a strip of VHB tape or 2 screws to attach the light to wood or a metal wall. The white light has a 1.5" metal disk magnet that would stay in place & attaches to the light. This makes it easier to remove and change batteries when needed especially on a metal cargo trailer. The white light is also adjustable by time - the brown is fixed. BTW they are both off during the day time.
