I got the bulbs the other day. They look very nicely built, but they definitely are not small! I got some pictures here.
I hope to get these installed on the Prius in the next day or two and I'll get pics with the headlights shining on the garage door at 10 or 20 feet away, and also a shot with them shining down a road or my driveway or something. I'll do this with a halogen in one side and the LED in the other for comparison.
Installing this on the motorcycle is going to be a bit more work. I'm pretty sure I'm going to have to cut out the back side of the bucket to make it fit.
