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,

 

A Bulb is out inspect the lights ..Or take it in the Dealer 06 should still be under warranty 4/50
