Mercedes Benz S500 headlights are your key to survival whenever you go out for a night drive. The last thing you want to happen when blanketed by the dark night is to blindly navigate the road without the help of these. One moment, you're casually driving with enough visibility. Next thing you know, the lights suddenly go out. Here are few scenarios to help you pinpoint the root of certain headlight problems. Different factors such as bad connections, faulty relays, blown bulbs, and many others are lurking nearby ready to give you a problem with your Mercedes Benz S500 headlights.
The easiest diagnosis for dead Mercedes Benz S500 headlights is a busted bulb. On the average, the bulbs should last around five years before these need replacement. If it seems new and fairly intact, the problem may lie in the sockets, housings, and relays. Make sure that these parts are properly connected so that electricity is able to run to the bulb.
If your Mercedes Benz S500 headlights only work on one setting-either in high beam or low beam mode-the probable cause could be something beyond the bulb itself. The first suspect is the dimmer switch you use to turn the headlights on. If that's okay, check the fuse and relay.
Mercedes Benz S500 headlights should provide enough light to safely brighten the road. If you feel that the beam feels weak, it may be because the lens of your headlight is dirty on the outside, or there is moisture on the inside. It's also a good idea to check if the lights are aimed properly and directly towards the road. The beam should be on the same level as the hood of the car. Other than these, the alternator may be having difficulty charging the lights. The right voltage range should be between 13 to 14 volts.
The Mercedes Benz S500 headlights may turn on, but it either flickers or the intensity between the two differs. Again, check if the lenses are clean and that the lights are properly aimed towards the road. The battery may already be weak and have difficulty powering the system. Your car may also require new wires and relays to be able to handle the load requirements of the headlights.
