Q: My Mercedes ambient light flickers — is it the connector?
A: Flickering ambient lighting on Mercedes-Benz W204/W212 platforms is commonly caused by a loose or corroded 2-pin connector at the LED strip rather than a failed LED module. Inspect the connector before replacing the ambient light strip.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
