I just got the 2010 e350 4matic. Am loving the car and discover new things everyday. However, this is the car with the non-leds for fog lights. The car has the dual round lights in the front and for the life of me, I cannot get the outer lights to work. Only the inner two come on when I switch the fog lights on!!!! anyone know how to switch on the outer two????????

 

the outer two could be DRLs (Daytime Running Lights)

Check your manual too.

 

The outer two are indeed DRLs.

It's probably a menu selection to get them activated, at which time they will automatically come on with ignition.

 

thanks guys. the outer non-led lights are indeed DRL's. The on-screen display allows adjustment for this. When it gets dark, the DRL's go off and headlamps come on. The inner 2 lights are the fog lights. thanks again for the help.
