2021 R1250RS Headlight - AZOKIE02 - 10-05-2023
I just noticed when riding at night that my headlight on low beam only lights on the left side (as you face the bike). The high beams light on both sides. Is this correct or do I have a burnt out low beam LED on the right side?

That's how the R1200RS worked........

That is by design ... the low beam ("dipped" in the UK) is the right headlamp only, whereas when you turn on high beams, the left headlamp is added. The left headlamp (alone) has a slightly different beam pattern and aim than the right (low beam) headlamp, so that combined the two together produce twice the light output with a slightly different combined beam pattern compared with the low beam.
Most modern bikes with two headlamps use this asymmetric lighting approach which leads to many who are unfamiliar to ask questions such as yours. You are not the first.

We've been stopped a few times in parking lots or gas stations to tell us one of our headlights are out.
Sure would be nice if the US would give up requiring bikes to run the low beam during the day even if the bike has good LED daytime running lights.

I agree. My Tiger has a nice DRL that only comes on by itself when the ignition is on and the bike is not running. Other than that, the DRL and the one headlamp "winking" is on. Over in Europe they have a low beam and high beam switch which allows the DRL to be on by itself when the engine is on.
I can understand why the DRL is enforced here though. You can see these people at twilight ...
