Have you pulled the throttle side and control and unplugged the little white connector on the circuit board? If not, do this and see if the lights go out. If it does you need to check the adjustment/condition of the front brake switch. The front brake switch is not a mechanical switch, it is a proximity detector that senses when a magnet gets close to it. When you pull in your front brake it pulls the magnet in the lever close to the proximity switch. If the proximity switch was not tightened down well enough it could have shifted and is too close to the magnet at all times. It is also possible, depending on the switch they used, that the set screw for the proximity switch was over tightened and damaged the sensor. Either way the dealer can fix it for you. You may be able to check the position of the sensor with out taking off the hand controls. Look down the lever from the side and you should see two round things that look like plugs. The one on the lever side is the magnet (glued in and not adjustable) the other is the sensor. You should see much of the sensor sticking out, maybe 1/8 of an inch or so.
If you think this may be it send me a private message and I'll try to walk you thru adjustment.
BTW: if you take the hand controls off keep an eye on the little brass ferrels on the end of the throttle cables, they have a tenancy to want to fall into the bars or bike.
