Hello All
I have searched the forum and Internet to no avail. But does anyone have photos of a DU 42 taken apart, as I am not sure if my parts are correct. My reflector has a slot above the main bulb, is this correct? Also it doesn't sit well in the housing.
What distance should the reflector be from the rim, ie where the glass sits.
Lastly I have 2 different types of housings for the ammeter/ light switch. One type has a 2" hole and the other 1 3/4" which is the correct type?

Darren, a slot sounds like a Miller reflector.

Any pictures??

Have no pictures of a DU 42 in my pc, but someone here will.

Cheers,

Hi Darren..An 1 3/4" ammeter is the correct size for an M20 (and most other WD bikes)....Ian

Hello Ian
Sorry I meant the light switch opening, is it 2" or 1 3/4" as I have panels with both sizes. The ammeter opening on either panels is 1 3/4" but light switch openings are the two sizes

Thanks Ron
Do you have any photos of the actual reflector, also what is the copper wiring around the ammeter.

email (option): Darrenacartwright@yahoo.com.au

Darren, it's been a while.







I make the hole for the switch at a hair under 1 3/4" (I took this photo and uploaded before I saw the correction regarding which hole).

Thanks Ray
So by the photo the reflector sits in the rim held on by W clips, so ithe reflector doesn't actually attach to the headlight shell. Hence why I had a 20mm gap between the rim and reflector,(bullet proof glass?) Anyone know where I can get the correct frosted glass?
Looking at your panel the light switch is a 1 3/4" opening as well as the ammeter.
So what does the panel with the 2" light switch suit??
Thanks all

Some coil ignition models, eg Panther model 65 had a larger lighting switch which incorporates an ignition switch with seperate key.
Probably similar combination switch was used on the BSA 250 SV C10.
And most likely many more.

Darren,

The slot in the reflector above the main bulb is to light the ammeter. This is actually a pre war feature which was deleted on later WD models. This reflector was fitted to 6.5" and 8" reflectors with the panel in the headlight.

Best regards,
Leon

Re the glass for light if your not going to use the bike in the dark i would put a blackout lamp on it.I carry a glass in my pannier bag just in case took a lot of finding though i think you may find one on ebay now.

Just take a picure of the type of glass to your local glazier, they can usually cut you a circle of it for a couple of pounds

Darren the copper wire is actually a resistor for the direct lighting system on a James ML.
You can get a good look alike glass from a friendly glass supplier. It's just modern bathroom window stuff. It's a little bit thicker than original, but works fine. Ron

This thread has been extremely useful. Can someone please post a few pics of the DU142 (8 inches) Headlight Ring? Where the ring meets the headlight glass. Have a ring very close to original but not quite the right shape. Thanks so much

If you are going to do a lot of fiding after dark take your rim to a sliver plater and get it replated.
I went to a joint in Marrickville ( Sydney ) and it was around $ 25.00.

The candle is not real bright so any thing you can do to help is a good thing.

Mine is fine on the back roads but you get "white outed" every time some clot comes up behind you with 10Kw of blinding white light melting the tar, so I do not ventuer into the barkness much in the city.

Funnily enough, someone else asked me the same thing today. He also called it a 'ring' but I call it a 'rim'. The silver plated part inside is the reflector.
Here is a close up of a DU142 . Hope it's clear enough? The rims for flat glass and domed glass are quite different. Ron
