Night light bulbs are small, low-wattage light sources designed to provide gentle illumination during the night. They are often used in bedrooms, hallways, and bathrooms to help navigate in the dark without disturbing sleep. These bulbs typically emit a soft glow, making them ideal for children or anyone who may feel uneasy in the dark. Most night light bulbs come in various styles, including LED, incandescent, and compact fluorescent options. They are energy-efficient and can last for years, making them a practical choice for nighttime lighting. Many models also feature automatic sensors that turn the light on at dusk and off at dawn.
