Loose wiring or poor contact, or a damaged headlight can cause electric bike lights not to work. Loose wiring or poor contact: Due to prolonged vibration and aging, the connecting wires between the electric bike's controller and the headlight may become loose or have poor contact, leading to headlight failure. This is what users refer to when the bike runs normally, but the headlight does not illuminate. Damaged electric bike headlight: It's important to know that electric bike headlights come in two types: halogen and LED. LED lights are generally brighter than halogen lights. Although many electric bikes now use LED headlights, many models still use halogen headlights. As a result, some users request shops to replace their halogen headlights with LED ones when purchasing an electric bike. While this can make the lights brighter, the mismatch with the electric bike's system can cause the lights to malfunction more easily, leading to burnout. Solutions for electric bike lights not working: If the issue is due to loose wiring or poor contact caused by simple wiring looseness, the user can reconnect the loose parts. However, if the problem is due to aging or corrosion, the connecting wires need to be replaced to resolve the headlight issue. If the electric bike headlight is damaged, the user only needs to replace it with an original bulb to fix the problem.

Does the Mercedes-Benz C-Class have Burmester sound system?

Mercedes-Benz C-Class comes with Burmester sound system. Burmester sound system effects: The front sound field's tweeters are upgraded with 3D rotating tweeters. In addition to the stunning acoustic configuration, the visual effects are equally impressive: when the system starts, the two tweeters installed in the door mirror triangle panels will light up together with the ambient lighting of the same color, while rotating outward by 10mm to the optimal position to provide the best high-frequency listening experience. Configuration: Although the Mercedes-Benz C-Class and Mercedes-Benz GLC also offer the optional Burmester sound system, they do not come with the original 3D rotating tweeters. The 3D rotating tweeters are part of the full 24-speaker 3D Burmester system equipped on the Maybach 600. When music is played, the tweeters extend and rotate, changing color with the car's ambient lighting. The high notes are crystal clear, and the effect is significantly different compared to the original car's tweeters, truly worthy of the 3D version Burmester sound system.
