Light is often difficult to come by while fishing early or late in a day, or at night. Headlamps work well. But I've found the Flex Neck Light by Energizer to be more useful, with far more applications. The light can be clipped on to just about anything, from a boat gunnel to a tackle box. It's also easily transported, its batteries last a long time, and its beam is "soft'' and broadly dispersed. Price is under $10.
