Headlamp dashboard seal

Post by klaus gerhard »

I wonder how to fit the sealing rubber to my headlamp shell. Is there a proven pattern and whats the appropriate diameter of the rubber cord?
Thanks
Klaus

Hello Klaus,

This is my 1950 light shell before renovation. The rubber was cut into three pieces and two followed the long black lines front to back on the shell with a short piece in the outer set of holes across joining the long strips. I hope this helps you?

Who knew that. When I renovated my headlamp, it had no seal; therefore I used edging strip.
This is the, new thing, that I have learned today.

I think they vary a bit. The one in my picture is marked as a DU42 - the SSU700 I have fitted to the Mk1 doesn't have those seal holes...

Great. That helps a lot. Did you use a 2mm rubber string?
Thanks very much

I bought mine from Drags, not sure what thickness was but reference 516524A and only £0.98 for a long enough piece. Looks like they reference it for all similar headlamp assemblies.

Apparently I bought 2 mm sponge EPDM round section, according to my historical eBay purchases!
