4k instrument cluster switches/driving lights

[Eric]

If things work out I should be proud owner of a set of euro light
assemblies soon.  These are the ones with driving lights (H4/H1 or
something like that).  My question is how to switch the driving lights.
I notice there are several unused switch locations around the instrument
cluster bezel.  Does anyone know if there are factory switches I might
find to put in these locations?  My car is a '85 4kq, and the owners
manual describes these as "unused" locations.  I thought maybe later
cars might have fog lights or something I could use a switch from.  I
would prefer US market solutions, but curious to all options.  I don't
mind fabrication, but I would like to maintain factory look.

Thanks
Eric
