78 C3 Headlamp "pots"

I am hoping to install a set of these from ebay: https://www.ebay.com/itm/357912262558
LED bulbs that are super bright and have a nice low tight beam pattern - which is great up here in the mountains!

issue is that the bulbs are deeper than the 78 stock bulbs.

i am in hopes of there being an aftermarket "pot" i can install so i can use these bulbs- but have not found one yet...

Anyone have any ideas?

Hello,
Welcome!!
I was curious about how this conversion works. So I looked at the link to ZIP.
It seems like a straight forward change. (Just keep track of what 'pot' goes where.)
BUT why such a LARGE difference in cost from ZIP bulbs to E-Bay bulbs?
Regards....

Welcome, there is tremendous development in lighting options these days what you do today may be obsolete tomorrow but will still be better than factory. Good luck.
