when I got my royal star last fall I noticed the driving lights hit the garage door a bit higher than the low beam
I was going to adjust them to bring them down, and quickly saw there are no adjusting screws, and the mounting seems to be fixed
The bike is a 2000 Boulevard model, the driving/passing lights came from the factory
diving a bit deeper, these lights are like a very wide angle lens - they dont really point or focus, they disperse light maybe 160° in a hemisphere in front of the bike.
They are wired to be on with the low beams, and off with the high beams, with a switch on the side of one to shut them off always.
The question keeps coming up: what are these 'passing' lights intended for?
they are not like driving lights we use to put on our cars back in the '70s. Those were high intensity quarts halogen focused spot lights that you used with your high beams. They would light up a dark road as if you had turned on the street lights and you could see 100 yards ahead like daylight.
they are obviously not just for when you pass another car
After riding with them for a few months, and noticing how they look on bikes coming the other way (almost always HD baggers) I think their primary purpose is to light up the front of your bike during the day so on-coming drivers can see you better - its like looking at the front of a GE diesel locomotive coming down the street with its three headlights. I think it gives drivers a better way to judge how far away your are and how fast you are approaching than the single point of one headlight.
I dont ride at night much, they light up the sides of the road better with the low beams, but I do get drivers flashing their high beams at me, thinking I have my brights on when I dont. If there is traffic on the road at night I usually turn them off, and use the high beam (only) when the road is empty. When the roads are empty and Im riding slower, like thru my neighborhood, I turn the passing lights back on.
So... if it was based on my experience they would be properly named "day time running lights"
