Its very difficult to correct this common problem, many where replaced under warranty. It is possible, it can be done by a specialist, my Ferrari specialist did it for me but it cost around $400 per headlight. They can remove the headlights and prize open the sealent on the units (they have to be VERY careful not the crack the perspex which would destroy the unit, this part is not available seperately from Ferrari, they come as sealed units). It is a very time consuming process and takes quite a few hours. Replacement costs are prohibitive as a new item. It looks like from the picture you may be able to do something less drastic once the bulb is removed but to be 100% perfect the only option is as described. Good luck!
