This instruction will show you guide on how to install a new Auxbeam LED headlight bulbs for Mercedes ML320 2003. For this model we need to do some modifications to make them stay in place because the facelift model that started in 2002 uses a different locking mechanism. The1998-2001 Mercedes W163 uses a different locking spring and led bulbs might fit without any modifications.

We’ll replace 8000LM bulbs for low beams and 7200LM bulbs for high beams.
