W/o knowing where you are and the vehicle codes for there, a guess is: lamps for front & back, license plates for front and rear, maybe directional indicators

Normally I would say you need everything a 1923 Ford Model T came with from the factory. That would be Headlights, rear view mirror, and at least one brake light on the drivers side. But this is modified and without knowing the state you live in you may need turn signals and another tail light. You local DMV should be able to answer your question.
