Hello: I have a mini phantom emergency-responder blue light that plugs into a car's cigarette lighter. Given how bright this light it, I would like to use it on the rear of my bicycle to make myself more visible when riding at night. To do this, I will need to hook it up to a rechargeable battery pack. Any idea how to do this??
Buy a 12V outlet that comes with a cord. Connect it to the battery pack and plug the light into it.
