I found a cheap LED single AAA light at Walmart. Its made by Dorcy and it's about $5. Its comparable to the Solitare in size (a little smaller) but still reasonably robust (I've carried one in my pockets for about six monthes) and with good battery life. I so far haven't had to change the battery at all.
