You mention in the first post that you couldn't find a light bar for the older leather Tour Pak?
There are many old threads about putting an LED light bar from Custom Dynamics on those older leather ones. It was an easy mod since there is a connector already for the wires from the LED light bar. You just call Custom Dynamics and tell them how long you want the bar and wiring, they will custom make it for you. It's installed by just cleaning the leather with alcohol and sticking the bar on with supplied tape backing then you choose to drill one hole in pack to run wires inside or just run wires from outside pak over the lip of bottom section (maybe protect with tape etc. to get wires inside)
Many members who had 2006 -2007 CVOs did this mod, most with red lens LED but I did mine with clear lens with red bulbs. It really got people's attention when they were behind you especially cars since they had trouble seeing stock brake lights down low if they were near you. I also used LED saddlebag spoiler light to get lighting higher and spread out somewhat.
If you notice that if any vehicle has their lights grouped together it tends to merge at a distance and that makes it harder to gauge distance. Lights that are spread out don't merge together as easily.
Here is a shot of my 2006 with the clear LED bar between the antennas. Sorry I don't have a night shot but the old threads about increasing rear lighting should have photos of other bikes at night.
