Reading and working with limited lighting conditions can be very annoying. That’s why this LED light cap is so useful. It can pass through a surgical-grade lens that gathers and intensifies the light so you can see up to 35-40 feet ahead walking at night or in the dark anywhere.
LED never needs replacing like bulbs, it instead has two small inexpensive lithium cells give 80-100 hours use. They are available in blue, white, olive green, red or yellow for $20.
