I'll dig out the bracket and start working on this. Once I have a good diagram I'll see what a small production run (based on the number of interested people on this thread) will cost. At that point I'll see what material and finish(es) people are interested in. Mine is steel and fairly thin. Obviously aluminum would be thicker. Might have one of each cut out to see what they look like.
At this point I don't plan on providing anything other than the bracket. This will be intended as a straight replacement for the Triumph factory lightbar, which is what I did with it when I first made one--I already had the factory kit I just didn't like the spacing. Everyone else can source their own lights and wiring. If you need help with that I can publish what size bolts I used and I would strongly suggest spending the $25-30 on the factory Triumph driving light wiring harness (I think the part number is in the Tech Vault, but it's definitely around here somewhere). And then you can buy really cheap Autozone lights or regular "cruiser style" lights or nice expensive PIAA lights. Whatever you want.
Sound like a plan? When I actually have some I'll post here and in the Vendor forum.
