The other two you can not turn on until you turn the origional one off

Stupid

This house is lamo

Only one Light can be on at any time ,but you can put any ones on you want one after the other if you like ,but you can only go upstairs once

Go outside and look at the windows

And know for sure which switch activates which bulb in all three rooms

Do you hear them turn on

Go outside and look at the windows

Nope @Abe Lover

This house doenst have windows

Lame

You can only go up or down stairs

No way of seeing

Do you hear em turn on

No

Shall I drop a clue

Or not

Yea

Temp

Turn on a light and watch the thermostat

No

I will tell you tomorrow ,good night

To see which room warm up by you highly inefficient lights

Haha

He never said impossible

Only joking

It is possible

Promise

OK I'll drop another hint

light doesnt affect the thermostat unless its close to a lamp

Bulb temp

smh

So we check our rooms by how hot our lightbulb is

a lamp bulb usually doesnt produce enough light to change the temp in a room

I think you did the riddle wrong

actually not usually

it never does

A windowless room contains three identical light fixtures, each containing an identical light bulb or light globe. Each light is connected to one of three switches outside of the room. Each bulb is switched off at present. You are outside the room, and the door is closed. Before opening the door you may play around with the light switches as many times as you like. But once you've opened the door, you may no longer touch a switch. After this, you go into the room and examine the lights. How can you tell which switch goes to which light?

Cameras sounds easier

Googled ir

Remember you can only have one Light on at a time but ,you can change them all before you go upstairs
