BMW R1200RT/R1250RT Forum

I have a 2015 R1200RT wet head with a low beam headlight issue. The center (low beam) went out on me and I replaced it with a Sylvania H7 silverstar bulb. after many hours of the most excruciating time I haver ever spent... might I digress.. It didn't come on . So, in the middle of preparation for Hari Kari, I happened to try the high beams, they worked fine. Here's the kicker, when I did that, the low beam came on. If I turn the bike key off then on again, the same thing happens, no low beam until I toddle the high beam, that's all it takes. The High beam can be off or on at that point the low stays on.
I also noted that the light bulb out dash warning light comes on when the bike is first turned on, then goes out. But without the low beam on. I am not sure whats going on.. any ideas? thanks!!

I'm pretty sure that on my 18 RT the low beam doesn't come on until I start the engine.  Do you start your engine?

Do you have DRLs ?  Keyless ??
I have both, and don't get low beam until I demand it (or the engine is running and it's dark).

I though of that too, and no staring the engine has no effect.  I don't have wireless, and I also thought I remembered the beam was on demand.  So I started it in the garage with door all down and dark.  Still does the same thing.

how did you resolve this issue

Unless it's changed from my 2005 and 2009 RT, the single center bulb is for the high beam.  Natch, it only comes on when thumbed on.  Have the wires to the bulbs been switched by any chance?  I'm totally with you on the torture and time required to change any headlight bulb.

Wetheads have lowbeam only in the center.
