My current layout is only 4x8 stuck into the second bedroom of my apartment. Being a smaller layout, I've forced myself to try and stop buying new things and instead work on what I already own. My latest project was putting LED lights inside the front of one of my vehicles. In this case, a semi. You can see in the photo there is a lot of light bleeding out - in the future I will fix that. Fow now the semi is packed up (waiting for a road or terminal to be parked on).
This was a super easy project. I only needed 2 screwdrivers, small amount of sandpaper, and hot glue.
I used the screwdrivers to take the hood off the truck (needed the real tiny ones).
Sandpaper was needed to sand the back of the headlights. They had a silver coating on the back of the plastic (i'm guessing to reflect light and make them look more real). I used some 300 grit sandpaper and removed that coating.
Hotglued the lights into place (I used EVAN designs LEDs that are ready for track power). Fun easy project, and now I can't wait to build some roads and do more vehicles.
