New strategy for my 3 y/o wetting the bed....any suggestions?

I can tell you my story on the potty training deal. My son is also 3, but is only potty trained during the day, because i've just recently finally got him to go. Here lately he has been wetting his pants during the day. I sat down and look at the times he was wetting, and guess what its when the tv is on. So i think my son doesn't want to miss the show so he decides to wet his pants, so he doesn't get much tv time during the day anymore and its spaced out not all together. So your son it may be the tv. Also make sure you have a light on for him to use the bathroom with. My son will not turn on the light unless he can see, he says there's monsters waiting in the bathroom on him, we've tried to tell him no such thing, but his imagination has the best of him. So i keep my hall light on, it shines in the bathroom enough he can go without turning on that light if he wanted.
