. Why do the headlights on my Mercedes-Benz E-Class keep burning out frequently in Pakistan?

Detail:
I’ve noticed that the headlights on my Mercedes-Benz E-Class keep burning out faster than usual. This happens even though I haven’t changed the bulbs for a long time. Could this be due to electrical issues, voltage spikes, o r poor-quality bulbs commonly found in Pakistan? What are the most frequent reasons for repeated headlight bulb failure in E-Class cars here?

Frequent headlight bulb failure in Pakistan can be caused by several factors:

Voltage fluctuations: Pakistan’s power supply can sometimes be unstable, causing voltage spikes that damage bulbs.

Poor-quality replacement bulbs: Non-genuine o r low-quality bulbs bought locally often have shorter lifespans.

Electrical system issues: Loose wiring, corroded connectors, o r a faulty alternator can cause inconsistent power delivery to the bulbs.

Overheating: Enclosed headlamp housings with poor ventilation can cause bulbs to overheat, especially in Pakistan’s hot climate.

Vibration from rough roads: Frequent driving on uneven o r bumpy roads can shake the bulbs and cause filament damage.

To reduce frequent burnout, it’s best to use genuine Mercedes-Benz bulbs o r high-quality aftermarket ones, inspect electrical connections regularly, and ensure the headlamp assembly is well sealed and ventilated.
