Having a bit of fun here and thought that a little quiz might be amusing. The photo shows a K100 headlight with the reflector removed and painted black.
Anyone know what is going on?
More pictures will follow.

Is this something to do with getting a HID lamp to work without excessive glare?

Ha ha, you want a black light to have the car in front of you glowing at night Smile
You would be more successful if you paint the bulb too.

It's for an alternative universe bike where dark matter shows up as light.

With the potentially imminent 'precision strikes' on Damascus, they're expecting a return to the glory years of WWII when all headlights  were covered or painted black?

Someone tell them it was the lens that got painted.

Well that didn't last long! Here is the next picture:


The Bi-xenon HID projector is now fitted to the painted reflector.
I shall replace the glass with a piece of black painted aluminium with a circular hole in the middle with some plastic glass in the hole. The whole of the front of the bike will be black with the 10cm circle on the front.
Th Bi-xenon projector was bought from ebay for about €25 and runs with a 35watt HID bulb for both dip and main beam. When you switch on the main beam the metal shield flips out of the beam with a solenoid. The 35watt HID gives out about 3 times as much light as a 55watt halogen bulb, I know that because I have retrofitted them to my car.
I can also fit two rows of 5050 LEDs as a parking light. I have also bought some black reflective tape from ebay that cannot be seen on the black bike till you take a photo with flash or shine a torch and then it reflects white.

Ahaa very clever, now its not so much fun on the other side of one of those lights, so when they are driving towards you and are night blind and trying to gauge where just beside you is to be roughly on their side of the road, and appear to you to be vearing errantly upon your aproach to them, dont you go blaming them for the pickle you are getting into now will you. Too much candle power can be a dangerous thing.👅

I think that was the case about 30 or 40 years ago! We are all European now.

Not sure about that as just about all car manufacturers use them these days. The reason for using a projector rather than just sticking a HID bulb into the existing headlight is that the projector is designed to eliminate any stray light above the cut off.
Perhaps if you think that too much candle power can be dangerous then we should all scrap halogen lights and go back to the old incandescent bulbs that kept you at 30kph at night.
I will carry on with the project.

This project is an example of why I love this forum.  People are willing to try genuinely new things to improve their bikes, and tell us all about it with helpful pictures.

I wish you the best of luck with it, and please do keep us up to date with how things are progressing.

Thanks for that. If i still lived in the UK you could have popped over to have a look as I was not that far from you. But hey the weather is better here!

I will not attempt to dispute the statement about French weather being better, but Suffolk can produce a drinkable wine:

Crazy Frog may be referring to the very nice bottle of Pecharmant that we drank while sitting in the sun at my house this summer, a good wine that we don't tend to export.
Love the reference to the 7 acre vineyard in Suffolk, I wonder how that compares in size with the average vineyard in this area

yes My mistake Bikerboy, I had a thought of the Ettamogah Pub cartoons we used to read in the mag called Aussie post cir 1976, a cartoonist ken maynard had drawn one of the cartoon charactors driving an old outback truck with huge driving lights that it was perported would melt tar at 300yards and I was doing an "oh by the way if" post but unless you had read most of the cartoons it would not have meant much so better off saying, should be good cant wait for the end results. There back in 2013 again.

The projector lens is the only way to go with the HID. Too many (ricers) sticking HID's in their stock reflectors over here..painful, and usually the wrong temperature to see any better

I had noticed down in Bordeaux there are a lot of wines that don't see export.......but quite a few are ones that really need to be enjoyed young and not up to the stresses of transportation- a decision made long before K bikes....

projector lens
Will this result in a more pencil like beam than the bikes origional spread of light?
Stock reflectors, I am guessing the stock reflectors are then out of sinc with the new bulb

A projector (not a lens, but a unit) gives the same beam pattern as a normal dipped beam but with hardly any stray light. The stray light from a normal halogen light is not too much of a problem as it is not very bright when compared with a HID Xenon light.
If you put a HID Xenon into a normal reflector made for a halogen bulb then there will be stray light everywhere which will just dazzle other road users. That is the reason that all factory HID Xenon equipped cars have a projector headlight.
Have a look at http://en.wikipedia.org/wiki/Headlamp which may help you understand.

Would it make a difference with the reflected/scattered light by painting it flat black?

No difference as the HID xenon bulb will not even be able to see the old reflector. All it will see is the inside of the projector part.
