Re: can u solve it
turn on the first switch for a while and off it and switch on the second one.
Then get into the room. the one which is glowing is for the second switch, the one which is hot is for the first switch and the other one is for the third switch. Last edited by Barbie : 01-12-2007 at 04:47 AM. |
