Are the extra lights a Triumph accessory or another make? Triumph's own ones are foglights not headlights or day time running lights. On the T/bird they are mounted higher than the ones they fit to most other models. The combination of these 2 facts could be the cause of the drivers reaction. I sometimes had oncoming traffic flash me when I have had my Triumph Explorer's foglights on even tho' they are mounted much lower than T/bird ones, so I very slightly adjusted their angle & direction away from straight ahead. That hardly changed their effectiveness for me but greatly reduced the flashes from annoyed other road users.
