Morning all Dug out the trusty steed from its winter hibernation all checks etc etc done , wife and I set off yesterday over to west coast through Glencoe down to Oban onwards to Lochgilphead back through Stirling stopped of at friends in Dunfermiline then north back to Perth
Anyway enough of what we did ,bike performed as expected until later in the day when brake failure light and warning triangle came on Arghh!!!!!! brakes were still working only 15 mins from friends so got there with no issues , had dinner etc came out after about 3 hours fired it up and all well again

Also first time had it out in the dark , full beam looking for aeroplanes , I believe there is an adjustment ?

If you have a handbook it shows you the adjustment knob for the headlight.  It can be set for solo or two up but it's normally too high.  There is a sort of plastic nut incorporated into it but this normally needs a spanner to turn it for more adjustment. Whole thing is white and situated on the back of the headlight. 
Brake light warning can be caused by low voltage.  If you can still hear the servo and there is no loss of braking efficiency I wouldn't  worry too much.  It's very obvious on the servo brakes if they fail as you end up with something BMW call residual braking which is not a lot.

Headlight beam-throw adjustment

Moving the pivot lever adjusts headlight beam throw so as not to dazzle oncoming traffic.

Is the rear spring preload set to suit the load carried by the motorcycle.

This thread from BMWLT, http://www.bmwlt.com/forums/rt-series/6 ... tment.html, has links to pages from the Rider's Manual & Adjusting Headlight pdf.

I seem to remember on my 2007 RT, having to run it with the pivot (white)lever in the heavy load position.

Didn't make any adjustments to either the height of the beam throw or lateral throw screws.
(This checking of headlight beam throw is part of an MOT Test.)
