Creating quality products for customers to conquer the night is the foundation of OLIGHT's business. Ultimately, their goal is to uplift users during the darkest moments.

The OLIGHT RN 400 is a rechargeable bike headlight with a maximum output of 400 lumens and a fast-charging USB-C port. Its "anti-glare" design directs the light beam downward to avoid blinding oncoming motorists or pedestrians, enhancing night riding safety on the road. The bike light is IPX7 waterproof, allowing it to withstand water immersion up to 1 meter, reducing the interference of rainy days on cycling.

The RN 400 features an easy-to-read battery indicator, displaying the power status with color-coded lights: green for 21%-100%, red for 11%-20%, and flashing red for 1%-10%. Designed with a mount, the bike headlight can be securely installed on the helmet, handlebar, or under a camera, making it suitable for urban riding and daily commuting.

Regarding the installation process, the RN 400 utilizes a quarter-turn style mount, making it easy and convenient to install and release. The anti-theft mount is highly secure, ensuring the headlight stays in place once installed.

The package includes the RN 400 bike light, a handlebar mount, four silicon straps, a USB-C cable, a 3mm hex, a user manual, and a bike mount compatible with the G-PRO model.

In terms of technical specifications, the RN 400 has a maximum runtime of 7 hours, a maximum throw of 292 feet (89 meters), and a light source of a TIR optic lens. The bike light's body is made of aluminum alloy, weighing 3 ounces (85 grams) including the battery.

Users should note that before the first use, they need to hold the power button for about 3 seconds to unlock the bike light. Otherwise, the button will flash red, and the light will not turn on due to the built-in locking function.

The RN 400 is designed to fit handlebar diameters ranging from 28.6 to 35.0 millimeters, including aero options, with three sizes of straps offered.
