This product is infrared radiation type, the light source has been integrated in the machine, no external light source required. Recommended for use in low light environments. The darker the ambient light, the better the machine performance. For outdoor use and strong light conditions, a light shield must be added. 2. When measuring the speed of the projectile with higher speed, please take appropriate protective measures, in order to avert the rebound of the projectile after hitting the machine and causing damage. 3. Observe the marking on the left and right sides of the light bar when installing, “L” for LEFT and "R" for RIGHT. The strip with the light is facing down.
