Likely a bulb out. If you're handy first try swapping side to side as these babies are quite expensive and if you buy from dealer they won't take it back if it isn't the bulb.. If you need a replacement search ebay..D1s is the lamp and they are about 1/4 the price as dealer..my dealer wanted $375...and you should change both at the same time as the lamps start to get bluer as they age and the new one won't color match the old (if that bothers you)

This is just an example.... theres cheapers ones too


but as murphy stated, take each bulb out on each side and switch them to make sure its not the ballast that burned out
