So your driving along the Motorway,country road and your coming up behind another car,you spot the whiteness of the lights,super bright,so you want this on your car and have a good look at the make of the cars with these super white lights and they are maybe a Seat wee family car and you think what the f-ck am i paying all this money for a mercedes when the cheaper cars have a better lighting systems,come on Mercedes your showing us up,its a Joke !! I have the Led High Performance and they are **** to be honest in comparison to ones im seeing going around,gets a wee bit emabarrasing when your having to pass them :-( and theres no way of changing the bulbs to upgrade it,they are a sealead unit apparently?

Just don't raise or leave on high beam like the guy you just saw.

Mr. J

Adjust them. Both my vehicles were aimed too low from the factory.

Yes - my car had the lights adjusted very low also.
One thing I don't like about the led headlights is they have a very sharp cutoff. So it's nice and bright but if outside the light pattern you get no light. With low beams on it's a little dangerous sometimes....when road is going up and down.
Old style lights light up more of the road as they are not so focused.

Are yours the adaptive LEDs? I have them and they're incredible, like driving in the day but at night!

1987C1

Yes, adaptive LEDs.
light is good, but only see exactly what's in front of you.
Biggest issue is when going down hill and then coming to a uphill section... uphill section is totally dark.
On my Toyota pickup it's old halogen lights are not focused and have extra light showing the changing hight of the road. Not very much light, but just enough to see.

The adaptive high beams on the C300 are fantastic. And no issues on twisty flat road. Issue is with low beams on....high are great.

Sounds like they need adjusting. Even on low beam mine are beyond anything I've ever driven and light the edges perfectly. Got to be worth a try?
