I just received a pair of LED 194 style lights that work great! Very nice construction and very bright 4-LED cluster. Here's a link to the guy I got 'em from on eBay:

He has quite a variety and shipped pretty quick. If you find something you like, be sure to look through all his auctions. I found the lights I wanted and they were over $12 with bids, but in looking further down his list I found the same lights with a Buy-it-now of about $7. So it pays to look. Anyway, just got 'em installed and they are about twice as bright as the original horn lights. I chose green since I've got the Dragon! I'm sure brightness is somewhat relative to color as well, and he did have some larger clusters in other colors. Here's some pics...
