i learned something valuable recently, regarding my decorative lights.
this goes for any of the decorative 10 light strings. i had tried replacing them with some other mini bulbs, but the ones for a strand of christmas lights doesn't have enough voltage.
here's what i bought at Ace Hardware (i purchased online and had ship-to-store for free).
see in the top right corner, "For 10 & 11 light sets/tree toppers" ? ... yep.
so, this afternoon, i got out my little ladder, and replaced an old bulb, and it's glowing like all the others =)
