but how do you turn off the light once you are already in bed?

There are a handful of solutions to the problem of the lights being on while in bed, but wanting them to be off. One way is to turn off the lights before entering the bed. Another way is to get out of the bed and turn off the lights and then return to the bed.

Another popular solution is to place a lamp near the bed, such that the light controlled by the wall switch can be turned off before entering the bed and the lamp nearer the bed can be turned off while in bed.
