So a while back I was naive enough to attempt to make a custom running/brake light using the existing reflector/bracket from the bike. Well, I am older and wiser now and know enough to NEVER try this again! Anyhoo, I did succeed at long last and here's the pic's of what it took.
Firstly, I ordered a running/flashing brake light from Custom Dynamics. That was the easy part.
Then, I disassembled the said light and removed/cleaned the existing reflector off the bike. I also used a 3D design software to design a custom housing that matched the shape and size of the stock reflector exactly:

I sent the data file for the housing to a 3D printer shop and a week later had the part printed in black ABS:


Since the housing added an additional 5/8" to the depth of the whole light compared to just the reflector lens, I cut the stock bracket by 5/8" and drilled to additional holes to pass the wiring through:

Now, it was time to assemble the whole thing. The toughest part since glue was involved!


Mounted the fender liner back and connected up the wires:
RUnning light:

And Brakes:

Overall, I am very happy with the result. But as I said the whole thing, especially the glue-without-making a mess part, was harder than I expected. So now I have the reflector/running/brake light as an all-in-one unit and the bike looks like before without any physical scars of any kind.
Only one regret:
I wish I could have found an LED strip that was longer since the reflector was wider than the light I purchased from CD. But the next size up would have been too big. Oh well, now that I know what it takes to take the light off and put it back on again, if and when HD sells a unit that actually fits my bike like it should, I can swap it out in a few minutes (ok, more like 30 minutes).
What do you guys think?
