Safety helmets with built-in lights are essential for work in low-light or hazardous environments like construction sites, tunnels, and mines. These helmets offer head protection along with integrated LED lights, improving visibility and safety. Common features include high-impact ABS or HDPE shells, adjustable headbands, and rechargeable or battery-powered LED lights with multiple brightness levels. Some models have front-mounted LEDs, while others support detachable or headlamp-style lighting. Rechargeable versions often use USB charging and offer 4–20 hours of operation. Look for waterproof ratings (IP65 or higher) for outdoor use. These helmets enhance productivity and reduce the need for handheld flashlights, making them ideal for night shifts, inspections, and emergency response teams.
