• maintaining a consistent appearance of the rear bodywork,
• preserving compliance with the factory lighting system,
• reducing repair costs while maintaining high-quality workmanship.

Selection and compatibility

When selecting a lamp for the Mercedes ML W166, it is crucial to match it to the specific body version and the side of installation.
