Default voltage / current (amps)

You are right. I am sure that's what he meant. less amps would be the correct terminology. With amps and current meaning the same in this circumstance.

langhammx - when I posted that, it made perfect sense (to me). Now that I see it quoted, I realize how geeky it sounded. Forget I said anything.

BTW, I agree on the light output of the LEDs. I think they will be a disappointment.

Good catch!
1/3 current is what they claim.

You need to try an HID.

You can see everything better with the HID set-up; eyes on the side of the road, reflective signs and painted road markings stand out much more clear than with Halogens.

After riding the bike at night, if I jump into the truck to go somewhere, it seems as if there is mud on the truck's lights.

Another benefit of the HID is driving in the fog; the road markings are much easier to see even in the heaviest conditions.

As I mentioned before, the HID set-up is extremely durable. I have used the same assembly on an off-road bike for two years with no issues.

I agree. And is why I want to see a side by side. Don't think it will even be close to the HID light output. (down the road output)

I bought one today. I ordered it off the internet and dont think that they are back ordered. I got mine for $275.00 shipped so they are not real bad. I am the standard harley dual beam with out HID. I will post some side by side photos when the light comes in. My only concern with the light is the fog. I have a led flashlight I use for firefighting and they don't cut through the smoke as well as a halogen bulb. Someone had to take the plunge on testing this thing out.

Looks like we have our guinea pig. Pics and results are required asap. Also where did you get it for that price???
