An optical headlight tester designed to test contemporary headlights as they become lower and lower. An aluminum structure allows E-light to increase its size, reducing its weight, stability and optical analysis. The structure is designed for one-handed movement, thanks to a counterweight. A new thin fresnell lens allows the collimation of a wide ray of light. The ergonomics of the object is designed to facilitate the use and movement of the headlight tester, which features a clean and essential style, bucking the trend of competing products.
