    I'd be interested too. Do you think a headlight shield would be possible?

    I would be interested in one of these set ups, feel free too pm me when you have a final price, as asked above a light guard would go well with the package.

    Any chance of seeing beam pattern photos? I have asked this of TT rally screen owners and haven't seen any so far. A comparison with stock would be nice (though unless you have a friend nearby with the stock headlight I know that is asking a lot)....(come to think of it, is there anybody out there who still has stock lights... Maybe one or two who never ride at night...)

    My plan is to use what Lynx fairings have, thick lens sticker.

    I was going to do that yesterday, but it started raining.

    It's actually quite easy for me to do, because I have a spare lithium battery.

    Yes that works well for impact protection but not so easy for the mud build up.
    I had a lynx setup for my te610 and it was a bit difficult at the end of the day when it was all dried up on a multiple day ride. Just my 2 cents.

    I'm still very interested :clap

    I totally understand what you are saying. But I'm a shallow guy, I don't like the look of a separately clear plastic cover. :lol3

    My other plan was to make a polycarbonate cylinder that press fits into the face plate. Imagine a clear cap that goes into the plastic shield right in front of the lamps.

    I agree with you, the cover would stand out. Unless the actual head mask had a recess. Lots more work.

    The clear cap would be a great option! It would have to have a perfect fit to avoid water build up inside. But given your skills, that should not be an issue. :D

    Obviously the brightness comparison would be fairer if the alternator is not running, so the volts are about the same, but I guess I am more interested in the shape of the beam anyway.
    I found my Morimoto projector puts too much light near the bike for my liking for highway use (though not as badly as the HID-in-OEM reflector setup I changed from). This is something that car drivers would not notice so much, typically having a hood that shields their eyes from this glare, but from my point of view the idea of a projector is to put light only where you want it and not waste lumens, and the glare doesnt help night vision, especially above that sharp cutoff. Yes, I am hard to please!
    This light spill might be okay for offroad use where seeing close to the bike while standing would be an advantage, but I havent night-offroaded this current setup yet and I figure I would be using my Rigids in that situation -while they throw a lot of light down the road, they also spill onto the foreground just because that is what LEDs do.
    Sorry for the partial hijack...just trying to give you a sense of where my thought train runs and why I decided to go to a projector - they are the ONLY way to go for good lighting IMHO. Nothing ticks me off more on a night ride than having someone who doesnt dip, or has badly adjusted headlights, and I dont want to inflict that on anyone else

    The cut off on the 90mm is OKAY, it's way better on the 60mm projector. But both are way better than any reflector style lamp especially with the HID conversion.

    I will take some picture tonight.

    Here is a picture of my 60mm projector. Beam angle is not adjusted, but you get the idea of the quality of the light.

    Please read this first.

    1. I'm a experienced photographer, and I will be the first to tell you it's pointless to judge brightness or color temperature of any light using a photograph.
    2. Having said the above. It is possible to compare the relative brightness and color difference of multiple lights if the camera was set to use the same exposure setting and that the same white balance is applied to all the pictures.

    And this is what I have done here. I took picture of the different setups with my camera on the tripod in manual setting (same setting for all) and use only the 12v battery to power these lights. I've set the white balance to 'Daylight' ~5000K, So the closest light to daylight will appear to be whiter, the rest will be more yellow/orange. It's not critical to look at the color but rather the relative color temp difference.

    I don't think I need to say much here. It's pretty obvious. This is why I love hella's projector never like or feel the need to add additional auxiliary lights.


    Also please don't make comments like 'My stock light looks bright than your picture' I based my exposure value (of the pictures) from the Hella Halogen. As you know you can make any given picture brighter or dakar. But just remember if I dial the exposure value of the camera up so that the stock light looks brighter in the picture, the other 3 picture will be that much brighter than they appear now.

    I also took a series of pictures in front of the projector from high point to a low point to show you how well the Hella cut off works. This will be true regardless of the bulb you use (halogen vs hid), It's just quality shit from Hella.

    I have been working with Bmac on this setup, and seen it in person. It really makes a huge improvement over the stock setup. The projector/ HID really provides a nice flood that would come in handy in any low light situation on or off road.

    Yep - the hella setup is much better than the OEM headlight - US or euro. Its almost dangerous riding at night with it.

    When you have the mounting plate ready to go - put me down for one and a loom.

    ...for your professional approach to displaying the relative brightnesses. Great job! As you have pointed out, its impossible to show how a beam pattern appears to the eyes. Even if you used HDR techniques to approximate what your eye/brain combination perceives (your eyes having a much higher dynamic F-stop range than any standard digital camera) the result would be only as YOU see it and not how anyone else sees it, and the way your eyes see it changes as you scan around a scene anyway.

    Your setup looks great - it seems the Hella projector throws more light down the road where it is needed and less in close to the bike. Does that seem to be the case?

    Nicely done! :clap

    When you get it completed I quite possibly would be interested in the mounting plate and headlight bezel. I can take care of the wiring/lights myself.

    Yes, very nice! I'm also interested in the mounting plate and the bezel. I performed a similar mod a couple of years ago with Hella lights (posted in ADV) but I don't have the talent to make a bezel like you did. Would be nice to put the finishing touches on.

    very nice, I will take a full set up when there ready. 90mm low beam w/hid and 90mm high beam w/halogen

    What should be pointed out, is HID conversions on most low beam lights (including OEM US or EU adventure headlight) is crap because the lens optics are what's used to cut the beam. So you always end up either blinding on coming traffic or have the light pointed down, so it's no good.

    These particular Hella lamps has a metal insert that cut the light sharply for on coming traffic and do not use the lens optics itself. So they lend themselves perfectly to HID conversion like this. They are also dam good with a halogen bulb BTW.

    when you get everything figured out I would appreciate a pm for the complete kit using all halogens. thanks
