beam

Morning all, I am aware of the two knobs to adjust the headlights on either side of the front fairing. I am happy with the main beam but wanted to adjust the full beam - searched the web and the manual but couldn't find out which side control which?

Added a Daytime running light to the forks to fill the black spot in front at night and a set of Aliexpress LED lights for width to High Beam at night.

This is probably going to sound like a really stupid question but I bought a 2015 Tracer yesterday and only one headlight works unless on high beam when both kick in. Is this just how it is? I know other bikes operate in this way but I wasn't sure about the Tracer.
