Headlight or LCM Issue?

My son's 2001 X5 has something wrong with the passenger side low-beam. The cluster displays the lamp warning and I've changed the bulb without out effect. I can swap the bulbs left to right and both work on the driver's side.

I've used a test light to check both sides. On the drivers side, I back probed the plug and the yellow wire carries voltage and the brown appears to be a ground. On the passenger side both the yellow and the brown seem to carry voltage.

Is this a sign of a bad LCM, is there a relay somewhere or do I have to keep digging for a short?
