Following from Tomlinscote I found this article that explains the markings - http://www.danielsternlighting.com/tech/...codes.html
Between the first 2 lines of text on the lens you should have an arrow marking that indicates the throw of the lights. In front of the bike, looking at the markings the arrow should be pointing to the right, when you're sat on the bike the arrow (and beam throw) will be pointing to the left. If the arrow is pointing to the left as you look at it and the right when you're sat on the bike then you have lights designed for right hand road use. I don't think you can adjust right hand use lights for left hand use so if you do have these you'll need to replace them.
If you have the correct lights then the tester is an idiot and you really should ask to speak with his supervisor so they can make sure he is properly educated and doesn't continue to needlessly fail other bikes.
