I have a 2015 S550 with just 50K miles and the low & high beams for one of my headlights are not working while the top and the bottom strip lights are working. The dashboard gives an error message saying check low beam. Can I replace just the low and high beam bulbs or the entire unit of the head lamp needs to be replaced. There is only one connector going into the light so am not sure if individual bulbs can be replaced. Also since the vehicle is just 6 year old, is the problem with the bulbs or its the ballast or some other issue going on? But again, if you have to think that ballast would be the issue, will the top and bottom strip lights work or their power source is different? This is complicated hence looking for some help.

IF the warranty is expired find a good 3rd party mechanic that can check out the situation. LED lights should last longer than that for sure, maybe it is the moister problem. If you're still in warranty than dealership it is for repairs. I know once my warranty expires I will use 3rd party mechanic for most of the usual stuff except that only a stealership can perform.
