When I was growing up in Sweden (a very long time ago) the Volvo 122 cars were in their heyday and extremely popular. Rally racing was the sport of the day and when you modified your Volvo it was the rally look that was popular
“Extraljus” as in auxiliary lights was all the rage to achieve the rally look and brand and style was very important as well. The Hella or Marchall lights were good choices but if you really wanted to be cool you added the big Bosch Rally Knick.
I found these on that auction site and they are in very good condition.
Short of building a rally car around these lights I decided to replace my small Hella lights on my 122S Wagon.
Turns out that these lights had 100 Watts Halogen bulbs in them. This should ne enough to melt the paint off the car in front of you.
They look right at home.
