The earliest GSA's that had the aux light switch on the handlebar did have the fuses on the right hand side. I did a bit of extra research and it appears that on the earlier bikes the fuses were in different positions. On the earliest bikes with the switch on the handlebar (0382) they were under the right front side cover, later (model 0380) it appears they moved to the left front (the manual is a bit unclear about this), then with the last (09/2009-on, 0470) models they moved to the position I described. I only found this after checking the different online owners handbooks, BMW's RSD unhelpfully only shows the one location for both the 0380 and 0470 models.
Both 0380 and 0470 models had the aux light switch above the left hand switchgear.
