I really like these GloveLitF lighted gloves. They come in very handy when workng in tight places. Even netter, they are waterproof. They can fit over other gloves too. They are made of Neoprene so they are soft and flexable. The gloves come with batteries but when u need to replave them, they use 2x CR2016 or 1x CR2032. Just make sure when you replace the batteries that you don't bend the tabs and that you have the correct alignment so that you maintain the waterproof seal. Replace the screw to the compartment. They have 5,000 mcd LED's so they are very bright. I think I need a pair for everyone in my family.
