OK, so this is probably going to be a somewhat lengthy thread, you've been warned. I've been doing a lot of riding in the dark on my 1998 Yamaha XJ600 Diversion since I got my motorcycle license in July 2018. Being the not-so-very-morning person that I am, I tend to start out late in the afternoon and often finish riding on the wrong side of midnight. Admittedly Norway is the land of the midnight sun, but the spring and fall seasons here in Norway's narrow west coast valleys come with some very dark afternoons and evenings. And so I found myself needing better light performance from my XJ600, because I've grown accustomed to decent headlights. My trusty Can-Am Spyder that I've been riding for a couple of years has 2x low beams and 2x high beams (all Hella projectors, I discovered...), and I installed Opt7 LED bulbs in the lows. I also added a 40W Lazer LED bar to the Spyder's fairing, which quite literally turns night into day on the road ahead of me. This was the kind of light performance I wanted for my XJ600 too. And so I went ahead and bought a fairly expensive H4 LED bulb from Cyclops, only to find out that the XJ600's headlight wasn't too impressed with its new bulb... the reflector and glass are probably showing their age, because the output hardly changed at all. The little gain I got was likely more from the fact that LED's offer full light output from their lowest rated voltage (usually 8-10 volts), whereas the halogen H4 that I replaced probably suffered from low voltage through the 20 year old wire harness. After googling for a few weeks I went out on a limb and ordered a Baja Squadron Pro, that I planned to install on the XJ600 fairing (like I had done on my Spyder). It wouldn't be pretty, but it would give me the same kind of light performance that I was used to from the Spyder - but in a much, much smaller package. Only problem was that although the high beam power lead from the H4 would feed the Squadron Pro, the low beam would still offer very poor light from its H4 low beam halogen filament. So switching from a great Baja high beam to a bad halogen low beam would leave me semi-blind on the road. I guess it was about that time that I started looking into low beam options, thinking I could fabricate some kind of solution to replace the original headlight. I searched for weeks for a new projector light that would fit inside the limits of the headlight housing, and came close to ordering a used headlight from ebay to modify so it would accept a projector light inside. Then it dawned on me: I know how to do simple 3D CAD. I've done some CAD work in the past, using Sketchup (free) to draw (on a very basic level) an extension to my parents' log cabin and some other easy stuff. Now would be a good time to step up my 3D game and learn new Sketchup tricks. That way I could design a purpose-built light module to replace the OEM headlight, and have it 3D printed. Luck would have it that not long after this realization, I found the perfect projector for my application from a company called Furore Products in the UK. It was small enough to fit alongside the Squadron Pro within the confines of the fairing's headlight opening, and cheap enough that I went ahead and ordered one. The ball was definitely rolling, but I had no idea what I was getting my self into....
