Truck Advertising Roof Sign 1:14 for Tamiya Trucks

This is an optional part for the roof of the Swedish 70s Truck Cabin in 1:14 scale.
It was a common sight back in the 70s / 80s to have an illuminated sign on the roof, showing the logo of the Company.
Drill in the Roof three 3mm holes.
There is a drill template in the pdf-file.
Cut a M3 thread in the outer holes of the sign.
Use 3mm LEDs or small light bulbs for Illumination.
To prevent the light shining through the sign body, you can glue some aluminum foil on the inside of the sign.
