I put twin spots on my Honda CB360. They were linked to the full beam and I had one each side on the crash bars.
All was great driving around London (I was at UCL) to warn cars you were there. But I remember flashing a guy doing 40 on the newly dualed A303 towards Stonehenge who was sat in the outisde lane as I approached at c 70
I flashed the lights and the draw was such the bike lost 10 mph.
