I'm leaning towards upgrading from my 40 year old Vetter to a Hannigan fairing. I have two auxillary low beams and two auxillary high beams mounted to the Vetter fairing bracket. The yellow rod between the lamps marks the approximate location of the fairing cross-piece that mounts to the frame. I want to do a similar lamp mounting arrangement on the Hannigan. This is a marked-up Hannigan frame bracket. The yellow line is about the same position as the lamps on the Vetter bracket. On the Hannigan there is enough room to separate the low-beam and high beam lamps-- the low-beams would fit on a tabs an the yellow line and the high beams would fit on mounting tabs at the mid-point (the red line) or at the top (blue line). Here is a P'Shop'd mockup showing the relative positioning of the lamps on the Hannigan vs the old Vetter: so I think everything will fit OK. Of course this is just the initial digital trial-and-error and the details will be worked out once I get the new mounting bracket fitted. How are you mounting extra lamps with your fairing?
