Center mark light indicator ????

[sea_bird200]

2006 E350...
at night when the head lights are on: My console indicate something like: "center mark light: left" or sometime changes to "center mark light: right" with a round light symbol on top .. Does anyone know what this mean ??? is this normal ??? or do I need to bring the car to dealer to check it out ???

Thanks,

I believe it is informing you of a bulb failure somewhere in your lighting system. I don't know what "center mark" means, but I'm guessing it's you center brake light?

ok: I got it..

It's the "Front maker light left" and "right" = the front right and left side marker lamp is malfunctioning.... and the manual indicated that I bring it to the dealer ASPS... does anyone knows where are these lamps located at ??
