Feature
Which vehicles does the Mercedes-Benz ML-Class W166 DRL Light Guide Strip & LED Board fit?
It fits 1 verified vehicle platform: Mercedes-Benz ML-Class W166 (2012-2015). Use the fitment checker on this page to confirm your exact year, make and model before ordering.
What options are available for the Mercedes-Benz ML-Class W166 DRL Light Guide Strip & LED Board?
It comes in 3 configurations: Light Guide Strip, Bundle (Strip + Board), LED Board. The Bundle packs the strip and the board into one set - one order covering both parts.
Is the Mercedes-Benz ML-Class W166 DRL Light Guide Strip & LED Board difficult to install?
Both parts live in the headlamp: the board is the light source and the strip spreads it, so the lamp comes off and opens to reach either. Replace only the part that has failed - or both while it is open.
Does the Mercedes-Benz ML-Class W166 DRL Light Guide Strip & LED Board replace the factory part?
Yes — it is built as a direct replacement for the OEM light guide strips and LED boards, matching the factory fitment points and connectors. You replace the two parts separately instead of the whole headlight.
Which DRL faults does the Mercedes-Benz ML W166 DRL Light Guide Strip & LED Board solve?
It targets the four faults these lamps develop with age: yellowing DRL lights, dim daytime running lights, partial LED failure, and a DRL that flickers or stops working.
What do I save by fitting the Mercedes-Benz ML W166 DRL Light Guide Strip & LED Board?
You only pay for the part that failed. It carries OEM fitment and connectors, so it drops into the original housing and takes over the factory unit's job - without the cost of a complete headlight assembly.
