Need some advice on a Super Chief project

[Carefree_Dude]

Alright, i've converted my super chief completely into power functions. I've so far done so without making any outside cosmetic changes other than IR reciver sticking up about even with the round pieces on the top. I even kept viewable engine through the window intact, made hidden power button for the batter box on the top, and hid all cords perfectly. It actually looks pretty nice. The one thing that bugs me though is that I only have one light hooked up, but there are two light holes. The bottom one is on the top of some SNOT bricks, so i can't run my second PF light directly to it. I'm trying to figure out a way to light up this part as well without any huge cosmetic differences to the set. I tried one method of reversing the two big slope pieces, but that left some bad gaps in the side of the train.
