2x Genuine Mercedes Sun Visor Mirror Micro Switches – Fits E-Class, CLS, W210, W211, W219 – OEM #2118700510

Alright, if your Mercedes sun visor mirror light isn't turning on when you flip the cover open, the little micro switch inside has probably given up.
This is a genuine Mercedes part – two of them, actually – so you get a pair.
They fit E-Class and CLS Class models, specifically the W210, W211, and W219 chassis.

The OEM part number is 2118700510 – also seen as A 211 870 05 10.

So if that matches your visor, you're good.
These are brand new, genuine Mercedes, not some cheap knockoff.

The switch is what tells the vanity mirror light to come on when you slide the cover.
Super tiny part, but without it, that little light stays dead.

Replacing it is pretty straightforward – you pop the visor apart, swap the switch, and reassemble.
Saves you from buying a whole new sun visor just for a bad switch.
One-year warranty included because Mercedes stands behind their stuff.
If your visor light works intermittently or not at all, this two-pack is a cheap fix that makes a big difference in convenience, especially at night.

And since you get two, you can do both sides or keep a spare.

Just double-check your visor style – this is for the mirror-type visors with the sliding cover.
Good quality, genuine part, easy DIY.
No more fumbling in the dark trying to find something in your center console.
Simple fix, big win.
