lighted "Star Destroyer"

this may be a dumb question but here goes…

I haven’t started it yet but , what is the sheet of foil for? The kit is: AMT/ ERTL with fiber optics etc… It has “4 chrome strips”. I haven’t seen in the instructions where exactly to use them. Maybe I missed something…Ya Think? Thanks in advance. Bob

I have the same kit also not started dont worry about the chrome strip it is for refecting light from the bulbs the hard part is putting holes in the star destroyers hull with the supplied drill bits.
