My 3HW was found without a blackout mask, tried to find one and finally bought what I think is almost right.

I don't really know how the entire unit of the headlamp is assembled though, maybe I'm missing some parts? Have not the correct ones?

Can someone please shed some light?

Kind regards,

Kostas

There's a flat cork seal that fits into the recess in the headlamp reflector..That seems to be missing from your photos...The rubber extrusion fits on an MU42 headlamp from memory, not a DU42...Ian

Ian,

Thank you for your answer, I used a flat cork seal between the reflector and the glass on my other DU-142 headlamps and the rubber extrusion between the glass and the headlamp rim.

Problem is the inner part of the blackout mask where the cork gasket won't seal.

Maybe a picture of the inside of a proper blackout mask will help?

Kostas, the BO mask with the brass plate (Does it say "Lucas Maxilite" or something?) Are a civilian hood. I'm not sure but looking at the inside of yours, I wonder if it's for a car headlamp. The WD motorcycle hoods fit just the same as a normal rim would and usually have the extra little round window. Ron

Ron,

It says "Lucas Maxlite" and it is for a car headlamp. I was planning to convert it for motorcycle use.
Do you have a picture of the inner part of a motorcycle mask?

Kostas, this is an old shot of the inside of a blackout mask - I think it is original.
The glass holder is a reproduction I made to replace a very rusty original.
The screws and nuts are not original either.

Well done Ray! That saves me looking or removing one:relaxed: Ron

Just seen this on the Belgium 2ehands.be website :
