Art, I’m sure with help from the expert forum members here, you could separate the forklift circuitry from the lighting, and turn them on individually. It will take looking into the soft underbelly of the building and performing some surgery, however. May not be for the faint of heart, but a cool modification, if one was willing to tackle it. I have cut the access holes in the bottom of Menards buildings much larger in order to gain access to change lighting configurations. Ya just have to go for it.
