Maintenance Essentials
Proper maintenance extends the life and performance of your BMW E30 headlights. Follow these key practices to ensure optimal illumination and appearance:
Regular Cleaning
Clean headlights monthly with automotive-grade glass cleaner to prevent dirt accumulation and yellowing. For glass lenses, standard glass cleaner is appropriate, while polycarbonate lenses require specific plastic-safe cleaners.
Restoration Techniques
For clouded or yellowed headlights, use a proper headlight restoration kit containing progressive sandpapers, polishing compounds, and UV sealant to restore clarity and protective coating.
Proper Bulb Installation
When replacing bulbs, always wear nitrile gloves to prevent oil from fingerprints transferring to the bulb surface, which creates hot spots that significantly reduce bulb lifespan.
Important: Never touch halogen or xenon bulbs with bare fingers. The oils from your skin create hot spots on the bulb surface that can lead to premature failure or even bulb rupture during operation.
