Is there any good home mods that are companion friendly and have functioning lights (the ones that can be turned on and off)? I am hoping for a mod like the one in fallout 3 (The bunker mod near rivet city and is inside a radiation shelter tube thing). I have looked on the nexus website but the ones I found do not look very good. Any suggestions?

Try the underwater home mod it's got functioning lights and has alot of cool features.

You're talking about the Underground Hideout mod, there's a http://www.nexusmods.com/newvegas/mods/37884/? for New Vegas. The aforementioned http://www.nexusmods.com/newvegas/mods/36121/? is also excellent, personally I prefer it over Underground Hideout anymore.

http://www.nexusmods.com/newvegas/mods/43757/? is also a very good house mod though it's smaller than Underground Hideout and Underwater Home. It includes a quest to fix the school up and turn it into a home.

None of these conflict with each other so you could have all three installed and then find which one you prefer in-game.

There's the Yangtze Compound, which is rather overkill if you ask me: http://www.nexusmods.com/newvegas/mods/44519/

There's actual house mods which are amazing like:

Rancho Villa http://www.nexusmods.com/newvegas/mods/46004/

Red Rock Ranch: http://www.nexusmods.com/newvegas/mods/35489/

Ravens Nest: http://www.nexusmods.com/newvegas/mods/46591/

Allright, I'll download all three and see what one I like best, thanks

The Underwater Home breaks my game for some reason

edit: So does the underground hideout. I'll try manually installing

Make sure you have all the parts of the underwater home, and I think it requires NVSE. You also need to run a Bashed or Merged Patch to get all the sorters working. To that end, use the Sorter Expansion mod for the Underwater home. It is a bit trickier to set up, but it is the best home out there.

Besides, if you can get the UW Home running, you want to defiantly stay away from any complex mods until you learn how to get them to work together.

There's extra Esps, that require masters not installed with the mod, like see you sleep, and non companion home + companion home, just untick the ones you don't need.
