Headlamp dashboard seal
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

Re: Headlamp dashboard seal
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?

Re: Headlamp dashboard seal
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.

Re: Headlamp dashboard seal
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...Chris Sealy wrote: Sat Nov 14, 2026 1:27 pm Who knew that. When I renovated my headlamp, it had no seal; therefore I used edging strip.

Re: Headlamp dashboard seal
Great. That helps a lot. Did you use a 2mm rubber string?
Thanks very much

Re: Headlamp dashboard seal
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!
