Yeh, dipped / full beam , but the side light opening was just a circle of clear glass so I used plastic padding to hold the bulb holder in place. This is how the blown one was setup.
My 1970 was the same, Im not sure if this was an upgrade done by some owners in the US, as all the stuff Ive seen for earlies shows the lamps as having separate reflectors and lenses. I would just fit new UK units with the pop out bulbs.
We normally use either beetle or Golf MKII units which most of the suppliers sell, I see slammedresto posted a link to an offering from Just Kampers where they were offering both lights for £38 which is cheap, you basically need a unit with a sidelamp either built in or the facility to take one,
