Basement Attic Light Switch Riddle

You are in a basement with three light.

Basement attic light switch riddle.

The light on is the second and the light off is the switch you didn t flip. Outside of the closet there are three light switches. There are 3 switches downstairs each corresponding to one of the light bulbs upstairs. The famous light bulb riddle.

Flip a second switch and run up to the attic. It s basically the same solution as our first idea. If you have 3 switches downstairs have a time delay of 5 minutes between each switch. One of them controls a lamp in the attic and two of them do nothing.

Go upstairs and touch the bulb. That is switch on 1 2 wait a minute switch off two and go to the attic and check if the bulb is on hot or cold. You can play with the switches as much as you want and after that you can visit the attic above just once. You are in the basement of a house where there are are three identical on off switches.

Compare the wattage on the light bulb with the rating printed on the light fixture. Test your brain logic by trying to solve this real life situation riddle. How can you find out which switch to which bulb corresponds. However you know the light is off to start.

There are three switches in the basement two of which are useless one is connected to a lightbulb in the attic. I was thinking about the light switches. If the bulb is cold. Then switch 1 would be the switch.

Switch 3 on 5 minutes then off. If you go upstairs to the attic you are not allowed to return to basement. Switch 2 on 5 minutes then shut off. How can you figure out which light switch goes to which light bulb by only making 1 trip upstairs.

As long as you don t stop for a beer before running up the light that s off but warm to the touch is the first switch. You have no way to see into the attic or to see reflected light from the attic. All of them are turned off and their switches are installed downstairs. Install a lower wattage lightbulb if necessary.

Switch 1 leave on 5 minutes then shut off. There are three light bulbs in your attic. The door is closed and you cannot see if the light is on or off through the door.
