That is a great idea... though changing out the bulbs isnt a problem really that is a much better idea.
I have used 2 of the same signs for 5 years in a row now and havnt had to change any bulbs out because I used the lights that dont break the circut if it gos out.

But you are right about the L.E.D. lights not using as much power.. I think this christmas I will be getting stocked up on the L.E.D.s
Also thanks for the props on the site guys... I will be adding some new stuff here soon, tis the season ya know...
Thanks agian..
