I know this has been discussed, but I need a 12 V. headlight for my '75 with stock headlight shell. Under "search", I find a Wagner part # for a Preston Petty replacement but no mention of a stock-size bulb. I'm getting ready to install the MZ-B and want to have all the stuff I need lined up.

Update: Since this post, I located a 12V. Wagner 4000 lamp which appears to be the exact diameter of the original and has the requisite three prong connection. We shall see, but it looks promising.
Keep us updated as to how it works.

Keithuu, I siliconed a Wagner 4000 into my Pentons head ligth shell and it works fine. Yes MZB equiped, use the clear silicone, the blue may explode [:0] (another story).

I got a fiberglass shell from Tom B. for my 74' Six Day and put a Wagner it in with a nice bead of 3M 5200. Its silicone caulk and super tough stuff. Once dry it has held in the light without any other means of attachment but removal will require cutting the bead with a razor.

The Wagner 4000 fit pretty well, tho' I did have to notch out the ring to accomodate the little "nubs" on the glass (3 places). I clear-siliconed the lamp in place both fore and aft, tho' it appears that the headlight will be held securely in the shell by the ring.
I was hoping to be able to re-use at least one of the headlight rubbers but the shape of the Wagner precludes both. I suppose it would be possible to modify the small rubber ring but I figured silicone would function as a shock absorber just as well.
The large retaining rubber is hopelessly oversize for the 12V. light due to its more rounded back.
With any luck, the MZ-B will go on this weekend and the lights will shine[8D]

Hi all,
I used a 12v Wagner 4419 in the stock large sized headlight on my 73 Jackpiner. It has a three prong plug on the back. I installed mine into the chrome ring using several small pieces of 3/16 clear fuel hose instead of the stock rubber ring. So far seems to be working fine.

Hey keithu, the MZB is a great ignition, and I know your gonna love the brite headlight [:p]. Keep us posted on the installation.
BTW, what size Penton ?

Raymond;
The bike is a 250 and I am indeed optimistic about the MZ-B's performance. The bike has been a 2-3 kick starter with the Motoplat so I can't hope for much better in that department. It runs fairly strong with only a slight mid-range roll-on flat spot which I attribute to a minor carb glitch, possibly just a needle tweak. I'm looking for a little more consistent fire and increased reliability cuz' we all know that a 30 year old Motoplat can become a "Motoflat" real quick.
Interestingly enuf, when I pulled the mag cover for the first time (I bought the bike with a fresh rebuilt engine), I found a notation on the flywheel indicating that the timing was set at "2.01 BTDC", which it is. The MZ-B's instructions say to set timing at 2.2mm BTDC so, despite the fact that I'm using premium unleaded, I'm a bit concerned about detonation. Hopefully that small change won't become problematic or detract from the ease of firing the old girl up. Stay tuned.[^]
