I know IPD offers a "daytime running light" switch that
they say can be wired to almost any car. It is listed in
the Vintage Volvo section. It has 200 series next to it in
the listing but also has 1962-1990 next to that. I bought
one for my 78 244 but have never wired it up...lol.
I would call and ask one of the guys if it would work
on a 122. Here's the link.

I don't know, but Ron Kwas might have something
like this at SWEM or he could at least tell you
if it would work.
