    Sure 'nuff.

    Looking closer at Hucky's lighting section, it also appears to be the very same lens he offers: 63 12 1 356 280

    The only question mark for me is the reflector. No markings to indicate where it's from. It doesn't have a place for a marker light, which caused me no small amount of consternation when trying to match the wiring to a diagram.

    What is the spring for in Hucky's H4 kit? I see that there are two holes on the retaining plate but I can't figure out how the spring ties into them.

    Lew, is that the same reflector (directly above) that you have that lets light through into the bucket so at night you have a faint glow through the indicator light lenses? If so, is now the time to paint it black?

    The set up I got from Hucky is "chrome" on the back side. Not really chrome but simply the bare, metalized plastic. This white paint, or whatever it is, would seem to be an improvement over what I have. And yes, now would be a good time to paint the back of the reflector. I s'pose.

    Josh, tonight's my last night on a night shift schedule. I'll be down at the shop tomorrow afternoon and pull my head light out and take a look. After six weeks of 6-day, twelve hours shifts, I can barely recall my name, let alonewhat the spring is for...

    edit -
    Okay, here's the deal.... funky as it is. The spring appears on it's way to sawing it's way into the back of the reflector (hard to see on this chrome surface, but the spring rides on the back of the reflector) I expect that, at some point in the future, the small lug with the hole in it (that the spring attaches to) will crack around it's base. Make sure you use six spring clips; the reflector will float around inside the ring if you don't.

    Thumbs up

    I have had this headlight sitting around for years and I am finally getting around to test fitting it.
    My headlight does not have anything that spring can hook into along the edge like yours does. Maybe it is a defect but the plastic tabs are solid.

    There are definitely places in the headlight that would allow a light leak into the rest of the bucket. It might be worth stuffing those holes with bubble gum! haha.

    It also seems that there should be a rubber gasket with this kit. The plastic and lens sits against the chrome trim ring and does not create a very good seal. I could easily see water penetrating through.

    And yeah, i could see needing many clips to hold it in place. right now I have 4 clips and the light is very loose. I'll have to dig through my stash for a few more.

    "should be a rubber gasket with this kit. The plastic and lens sits against the chrome trim ring and does not create a very good seal. I could easily see water penetrating through. "

    The gasket is absolutely necessary - I wrecked a similar product sold for /2 - PO installed no gasket
    After an all night rain at a rally the headlight area was about 1/3 full of water - I did not notice
    When I turned on the light the H4 exploded
    When I foolishly tried to wipe the glass bits and other crap off the reflector the silver came off as well
    Learned the hard way to never touch the silver with ANYTHING and keep the water out

    Sound like that must have been a real frog choker!

    The only gasket in the OEM head light assembly is the one that seals the perimeter of the lens/reflector (which also makes it "cleanable" on the inside). The bulb base does not have a gasket, but is somewhat more protected by the fitting on the reflector. I guess at $115 we gets whats we pays for ... the "real" H4 conversion kit runs around five Franklins.

    I wasn't' too happy with this set up when it came. Hucky wouldn't take it back because it's "an electrical part" (???) I offered to pay for a "replacement" bulb (the only real electrical component) but no deal. So if anyone is considering this set up, Caveat Emptor!
