My gen 1 05 reg has high beam, flash pas switch, hazard warning, indicators and horn.
On right switch , has start button and engine stop switch. No light switch.
As far as I'm aware earlier models had separate light switch on right switchgear.
Could be earlier models didn't get hazard switch, on left switchgear, maybe yours has older switchgear on the left bar due to repair?
Check to see if you have seperate light switch on the right bar, this may tell you your bike is fitted with earlier model switches.
Hope this makes sense
