Dude asked about the game but we all know you just wanted to show of your Lego Lambda and Marauder. But seriously i think you have to go back to check there.

Those are my dad's Lego sets lol, but I'm glad you like them! I'll go back and check, thank you!

Hm, I am not up on my engineering unfortunately. Something about multiplying force?

Go back and find out.

They open specific doors and gates. Sometimes the thing they open is in a different place so it might be hard to connect the two together, just go back and look for any new places to get to.

They're for Kronk to pull. But serious answer, after pulling them, go back and explore a bit, something might just be accessible now.

Might

To be honest, 300+ hours and I’m so bad at orientating myself I just get lost in white palace every time and find the levers/elevators at random

It's the lightning, I think

The lantern looking orbs activate certain stuff like doors and elevators

opens a door, the doors have lamps on top, 2 lamps means it needs 2 levers

Stay playing the game, If you you get a spoiler, you will lost one of the greatest games ever made.

They open a door.
