Any LEDs that I've seen like that wind up being more like DRLs than driving lights. Unless it is an LED with a housing (reflector and/or lens) as a unit, it just isn't going to throw enough light in front of you to be worthwhile.
I could be wrong, though, and for that price, I'd give it a try. But don't expect it to have anywhere near the light available from the H3 halogens you are replacing.
I'd suggest a set of H3 HID replacements instead.
