What are Lighting Requirements of Trailer that is Longer than 30 Feet

Question:

I am looking at building a gooseneck trailer and right now it’s 30ft and a triple axle trailer. I am wanting to extend the trailer to maybe 38ft or 40ft. What do I need to have for sure in the trailer. I live in Indiana if that helps.

2 Tail lights
2 Turn signals
2 Rear reflectors
1 License plate light
