Got a bulb out in your rear light assembly? Or a warning light on your dashboard?
The bulbs used for replacement can be picked up really cheaply here: amzn.to/4cEMJ8O
It is confusing when you first look at them, so this video shows you the location of all the different bulbs in your Mercedes nearside (passenger side) rear light assembly. This will enable you to change the bulbs for: The reverse light, indicator light, brake light, and tail light.
Also, as a demonstration, in this video I'll change the tail light bulb, and show you how to remove the bulb holder.
Note: Make sure you have the correct bulb for your application. You can search online to match the bulb with your model of car.
