Linked brakes - R1100RT

I'm on an R1100RT loaner of undetermined age, and I'm wondering if the front and back brakes are linked. Also, why are there two ABS lights?
 
The brakes are not linked.

As to why there are two ABS lights rather than one ... it's a mystery to me. Perhaps at one time they indicated whether a fault lay in the front or rear ABS unit. My 2000 manual, however, doesn't make any distinction. It just says that a fault is indicated if the lights flash in an opposed pattern (one on, one off). The manual doesn't actually describe anything that couldn't be indicated with a single lamp. So my guess is that a design change occurred somewhere along the line, but the cluster layout wasn't altered.
 
Thanks for the info!

BTW, it looks as though having the side stand down inhibits starting, even if in neutral. The starter works only when the side stand is up. Is this normal?
 
Yes, there is an irritating side stand switch that cuts the starter.

It should also start in any gear if you hold the clutch in. If it doesn't, the clutch switch is faulty.

The different way the two lights flash will indicate different problems. The lights can flash alternately or together, for example. How are you going to do that with one light???

Flash it fast or slow. Common on tech products with a single indicator light.

They could display further variations, such as one flashing vs the other flashing, but I don't see anything that suggests they're used that way. There appear to be only four states - on, off, flashing opposed, flashing together. And as far as I know, flashing together only occurs at startup, while the ABS is sorting things out.
