Mudder 2 Pieces LED Clip on Cap Lights USB Rechargeable Cap Flashlight Clip Waterproof Ultra Bright Hat Flashlight Headlamp for Christmas Fishing Camping Hand Work(Black, Red)

Mudder's 2-piece LED clip on cap lights are USB rechargeable and waterproof, perfect for fishing, camping, and hand work. The runtime is not specifically known, but reviewers have used them for several hours without having to recharge them. They come packaged separately and are packed in a bag. The USB cable used for charging is USB 3 for one end and USB C for the other, and the cable is included. There are two buttons, but reviewers suggest only using the left one. The lights generate about 100 lumens each and cannot have their batteries replaced. The clip works well on thin objects like the bill of a baseball cap. Reviewers are generally happy with the purchase, with one reviewer saying they would buy it again when needed, and another saying it's a very handy flashlight to clip to your cap. One reviewer used it for night fishing and found it bright enough for rigging and dehooking. Some reviewers did have issues, with one saying the housing is flimsy and the different light functions don't work as advertised. Another reviewer also had trouble with the head adjustment not working as hoped. Overall, Mudder's LED clip on cap lights seem to be a useful and functional accessory for outdoor activities and hand work, with some reviewers experiencing issues with the product's durability and functionality.
