if you're talking about the landing lights, you just have to make adjustments in the aircraft.cfg file until you get it right.


the instructions that came w/ the shockwave lights explain it;

take FS9 out of full screen, and pull up the .cfg file so you can tab between the two. after you make an adjustment, click "reset flight" (assuming you started your flight w/ the 777-200 and at night) to see the changes.
