Question about 2007 Mercedes-Benz ML320 CDI
BOTH LOW BEAB HEAD LIGHT OUT , THE LAMP IS OK BUT IT WONT COME ON HIGH BEAM WORKS
SOURCE: high beams wont turn on.
First place to start is with headlight switch. I did have a case many years ago when both high beams were blown out at once, but this is rare. When you have the headlight switch out, jump power from te low beams to the high beam contacts. If high beams come on, replace switch.

Go to autozone and ask them to put it in for you..lol or o'reillys. Youd be surprised at how much they will help you if you ask, It would be hard for me to tell you how, but under your hood on each side of your radiator, you can probably see back of headlight. If not it may have to be removed, just look how it is held in place, If I didn't help you I will if you will provide me more info, I do this for free to help people, please give a me a good rating, I don't have anything to gain by trying to help but for a better rating

You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.
I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp

At first 1994 C280 high beams began to not connect regularly when stick pushed forward, then not at all. Drove high beams by pulling and holding stick back towards steering wheel until that stopped working, too. Shop said the turn signal switch was at fault-- had seen it many times before with W202; about $160 to replace. Haven't done it yet, but should be an easy fix?

If you are absolutely certain the bulbs are okay, then change the switch. I would check for power at the socket first, to make sure it isn't bulbs.

There may be a relay that operates the low beam lights, check the owners manual to see if there is a relay, you should be able to hear it go "click" if there is one.
