*The maximum score is 100 points
Installation of the H7 halogen car bulb proved to be extremely quick and easy. It was particularly pleasing that no error messages appeared in the on-board computer, which enabled smooth integration into the vehicle. With a light color of 8500 Kelvin and a luminous efficacy of 1500 lumens , the product provides a bright and clear light that clearly outperforms conventional warm white headlights. Drivers benefit from a high-contrast light that reproduces road signs, objects and obstacles in natural colors. However, it should be noted that xenon or LED headlights are still brighter and the manufacturer only advertises the xenon look . This is created by the lamp with its sporty appearance and cool white-bluish light. At the same time, it does not dazzle oncoming traffic. The product is also compatible with a wide range of vehicles and is primarily used in twin headlights for high or low beam. Thanks to the E-mark, immediate installation is possible without registration .
