A penlight, also known as a pocket light, is a small, portable flashlight. Penlights are typically powered by one or two AA or AAA batteries and have a single LED or incandescent bulb.
Penlights are often used for close-up illumination, such as reading, writing, or working on small objects. They are also popular for camping, hiking, and other outdoor activities. Penlights are relatively inexpensive and can be easily carried in a pocket or purse.
