How to Deal with Mercedes-Benz Headlight Flashing and 'Stop Operation' Warning?

1. During daytime or nighttime engine startup, listen for any abnormal noises when the lights automatically adjust, and observe whether the light beams on the ground are shaking. After the shaking stops, check if the 'Intelligent Light System Stop Operation' warning appears. 2. Open the engine compartment. There are two white adjustment screws above each headlight (left and right) for adjusting height and width. Use a long Phillips screwdriver for adjustments. 3. Avoid excessive adjustments. After each adjustment, turn off and restart the engine, then observe the adjustment effect after the light self-check. 4. If abnormal noise or shaking occurs, identify which side is affected and adjust it by referring to the opposite side. Note the automatic adjustment trajectory—if noise occurs when turning right, adjust left; if noise occurs when turning up, adjust down. 5. After completing adjustments, test with high and low beams during left and right U-turns. If the 'Intelligent Light System Stop Operation' warning appears, the beam pattern of the problematic headlight will change. Note the steering direction that triggers the warning, then adjust the affected headlight in the opposite direction after stopping.

When the Mercedes headlights flash to indicate a malfunction, my first reaction is always to find a safe place to pull over and inspect them. I turn on the hazard lights to warn other vehicles—it's too risky to keep driving at night. After turning off the engine, I check the fuse box, usually located under the driver's seat or in the engine compartment, and refer to the manual to locate the headlight fuse to see if it's blown. If it is, I replace it with a spare—a simple fix. If the flashing persists, it might be due to a worn-out bulb or poor contact, so I remove the lamp cover to inspect, clean the connector with a cloth, or replace the bulb. For Mercedes' LED lighting systems, I avoid tampering as it could damage the control module. Last year, I recall an instance where the flashing was caused by unstable voltage, and the dealership later diagnosed it as a generator issue, costing a lot to repair. During routine maintenance, I always remind the technician to test the lighting system to prevent sudden failures. Safety comes first—get professional repairs as soon as possible.

When the headlight flashing warning appears, I believe it's essential to quickly troubleshoot common issues. First, confirm if the bulb has reached the end of its lifespan. Mercedes bulbs typically last several years, and replacing them isn't difficult as long as the model matches. For electrical aspects, check if the fuse is intact and try replacing it with a spare to test. Poor contact in the wiring is also common; simply unplug and replug the headlight connector to remove rust or reinforce the connection. If it turns out to be a control module fault, remember that Mercedes' electronic systems are complex—avoid DIY repairs to prevent damaging the computer board. Using an OBD scanner to read fault codes is recommended for preliminary diagnosis. Stay calm during the process to avoid minor issues escalating into safety hazards. Performing a quick light check before daily drives can save a lot of hassle. If unresolved, promptly contact a 4S shop or repair shop—paying for peace of mind is always better than risking an accident.

I encountered a headlight flickering warning and immediately stopped the car, turned off the engine to check the fuse condition. If it's blown, replace it with a new one and test whether the light can turn on. If not, check if the bulb is burnt out or loose, and try replacing it. The Mercedes system is sophisticated, so avoid disassembling it recklessly to prevent exacerbating the issue. For safety considerations, park the car properly and call for roadside assistance to wait for a tow truck. Regular maintenance should emphasize light inspections to reduce risks.
