An integral battery, light and light switch assembly can be removably fitted within a light-transmitting pocket on an article of clothing, such as a glove. Alternatively, the assembly can be mounted to virtually any surface with an adhesive or hook and loop fastener. In one application, the assembly can be attached to fishing tackle to attract fish. The assembly is particularly useful for nighttime use by those in the vicinity of traffic, including police, fire and ambulance workers as well as runners and cyclists. The assembly can also be used to mark a trail or identify a location in the dark. Infrared lighting can be used for tactical operations.
