Cost of xenon bulb for E550?
My dad says he found bulbs for my car online as low as $75.
What is realistic here? Also, any opportunity to "upgrade" my bulbs to something better than what came with the car?
Thanks in advance! I searched the forum but couldn't find much on this subject.

plus maybe 20-30 min on each side to remove fender liner(even though i believe on one side you dont even have to) and you saved yourself some $$$
P.s original Bulb temperature is 4300K from factory
i personally have used 8k before , but then changed it to 6k which is optimal for light output color and brightness.
also heard/seen that 5k is awesome too.
oh and your indy quoted 160 because its 'MERCEDES OEM" which is always more expensive

Each time it happens, as soon as I start the car the right low beam doesnt turn on and I get the message. It will remain off until I turn off the car and by the next time I drive it, it's on again.
I'm not due for service for 5,000 miles so I'd rather not make a trip to MB for warranty stuff unless I have to. I'm kinda hoping it's just the bulb but wanted to explore my options before I do anything.
Your adaptive high beam warning is concerning. Apparently if there is a problem with that system the car will shut down the entire unit.

Same year, same car, same lighting system.. similar (not exact) symptoms. What I meant is that if there is a problem with the high beams, it seems like the car will simply shut off the bulb on that side - even if there is no problem with the bulb/ballast. I just wanted to make you aware that it may not be as simple as the bulb before you waste any money.
As for LEDs being superior, no. Perhaps factory LEDs, but not an aftermarket kit VS factory bi-xenons.

My 2016 came with factory LEDs for the low beams and DRLs, however the high beams were halogen so i replaced them with a H7 55w LEDs. They are very powerful lights, i spent around $100 for the pair along with the pieces that lock it into place in the factory light slot.

Let me get this right, your car is still under warranty but you want to repair it yourself. Do yourself a favor and bring it to the dealer and save yourself a lot of time, headache and money. The bulb is not covered by warranty, but the ballast and module are covered.
If it is more then just a bulb issue you might cause yourself more of a headache by doing this all on your own. I'd take it to the dealer since you're under warranty and getting multiple messages.

Back to the OP situation, if the OP has time to kill, swap the bulb, that will tell him for sure if its a fail bulb or not without spending any money. If it is not the bulb, then bring the car into the dealer for warranty repair.

We carry high end Morimoto xenon units if interested, but can also get you top of the line Osram Xenarc CBI units as well.
Projectors are certainly better than reflectors but keep in mind that the projector is design for HID bulbs, not aftermarket LED. The focal point of the light source is different on the aftermarket LED bulb when compare to HID. The LED will look whiter, but functionally, the HID will be better.

The message "adaptive high beam assist inoperable" tells to me you have Bi-Xenon lights, right?
I have Bi-Xenon lights and I don't think I have a separate Hi and Lo bulbs. It looks like the difference between Hi and Lo beams is controlled with a shutter. This shutter also controls how far the low beams extend, i.e. is the Adaptive High Beam controller.
If you have Bi-Xenon lights I don't understand why the car would tell you "check right low beam".
