Approximate weight of headlight?
Can anyone give a probably-fairly-reasonable guess on the weight of the stock headlight?
I read a post once that it is "heavy," but I really don't know what that means. If for example it is 10 lb then I have got to do something about that! If it is four pounds then I do not!
I could check myself, but It would be significant trouble to remove the fairing and headlight just to weigh it, if someone already knows. So if anyone has held it in their hand and have a reasonable guess on what it weighs, that would be much appreciated! Thanks!

I have one sitting here, it weighs 5lbs according to my weight scale. (give or take a quarter-pound for error)
Bergie will probably get ya down to grams.

Ah, it would have to be that, at the range where it's enough of a potential saving to be worth doing along with getting a CF race-style fairing, but not so much weight as to make it dead obvious I need to!!
It's different part numbers for A and B models... is that a B model?
Also thanks to Bergie, his figure will also be helpful and especially so if his is a B and yours is an A.
What the concept is, is that I've seen these tinly little HID's that I doubt weigh over 2 lb if that including the electronics, that each of the pair puts out the same light as a 76 watt halogen.
If the stock headlight weighs 5 lb, they weigh 2 lb, and if a CF race style fairing (that I'd have to cut tiny holes into for the little HID's) saves 3 lb, then that would be 6 lb total which really would be worth doing.
Here's how tiny those HID's are -- not that of course I'd be mounting them like this:
Here's a truly crude mockup of how it might look, though my bike is black:
(Actually, don't know if that will work due to weird Yahoo URL.)
A shame though (for my purposes) that the stockers weren't more like 8 lb as that would have been more dramatically worth doing... but 5 lb still sounds worth going after. Thanks!

If you look at the photos of my bike, a tiny headlight looks good.

Sure does!
A single light? If you don't mind my asking, what kind is it? In case it might be a better choice than the above little HID light or lights. Thanks!

trenance, keep in mind the light pattern from those units probably won't be anywhere near what the stock lights put out. they tend to be a plain old round pattern like regular house lights, not the carefully shaped pattern vehicles use. that's not to say they wont work mind u. i use offroad lights with plain non-vehicle halogen bulbs. they work ok but certainly don't have the nice shape of the stockers.

Ah, that makes a lot of sense, at least as a possible risk, and probably the case that there's some issue with them.
The site that sells that specific one has one version that allows a choice of patterns, supposedly 12 degree "flood" and 6 degree "spot":
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=1393
Which sounds pretty narrow. If anything, too narrow even at 12 degrees.
However the version that comes as a pair together with controller offers no option as to the pattern:
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=1333
nor any statement of what the pattern is.
The photo supplied looks quite broad though as you say, with the right pic being the HID light, a single one I think:
It certainly doesn't seem patterned like the stock headlight but doesn't seem too bad?
Actually, doing the math, 12 degrees would be 15 feet wide at 70 feet, 30 feet wide at 140 feet, 60 feet wide at 280 feet, etc.
The above pic would have to be the 12 degree wide light I'd think.
While 6 degrees wouldn't spread to 30 feet wide (which seems to me would be a nice width) until 280 feet. It would still be reasonably concentrated light, only 60 feet wide, at 560 feet.
Maybe the thing to do there would be to have one 12 degree light and one 6 degree light?

I am not sure, picked them up at advance auto parts. they fit the countour of the bike well. it is not a high/ low beam. but, it is legal for street et, and any street class racing, and looks better than any 12 front end I have seen in my opinion.

It's got to save a lot of weight! Nox do you have a better view of the lite install from a couple of different angles and the front as well?
