When I was modding a set of 01 tails for led's, I forgot to tape up the socket holes & got a ton of water inside. I wiped out as much as I could reach & stuck the hairdryer in each hole until everything was nice & dry. Works like a charm.
I wouldn't heat the led tails too much, it's possible to melt a connection... then you've got an all new problem on your hands.

Also, if you've bought any electronics lately & have a handful of those silica jell packs, you could rip them open & pour them in the lights to suck up the water, but it will take forever & getting the beads back out will be a chore.
