I recently picked up these replacement LED bulbs on eBay for my halos (from a recommendation from another member here):

SOOOO much brighter and better looking. Literally no comparison. Can't speak to their longevity but for $11 it was a no brainier.
Now I just need to have my DRL coded off. And then I'll wire the halos to run all the time. Still looking for a easy-to-follow "how to" on doing that...
