Reddit reviews HKBAYI 50Pair / 50sets 3 pin JST SM Male Female plug LED Connector Cable For WS2812B WS2812 WS2811 LED Strip Lamp with 15cm Long Wire

Here is the BOM:
Got these because they were black PCB, don't like the way it was waterproofed but actually worked pretty well probably more robust than the coated ones.

This was the controller I used (I'm sure you can find them without the LEDs, it's Bluetooth which isn't as common as you might think)

I also used some nice outdoor rated PSA foam tape to hold everything on along with a few black zip ties just in case. Wired everything and sealed with silicone. Make sure you don't serialize the strips they should be all connected in parallel so they chase in unison.
They are connected to my AUX power output using the standard automotive 12V plug. They come one when my bike does. Which is fine. If I want to turn them off you can do so from the app for the controller.

That's it. Now to start on the custom controller. Anyone connected to the CAN bus on this bike? That would be the easiest way to get speed.

Mobile Users: This is pretty photo heavy.

I've worked on this over the last two and a half weeks in the evenings and on weekends. I've probably got around 50-60 hours in so far.

The project is complete, there are just some other things I'd like to eventually do with the programming for the LEDs.

Tools

Exacto/razor blades

Heatgun - for heat shrink, you can just use a lighter

Soldering Iron

Phillips Screwdriver

Laptop/Computer for programming with Arduino or CircuitPython

Printer - laser or inkjet

​

Supplies/Parts

Various Rustoleum Spray paints - $20 total

Multi-Strip - $15

Masking tape and paper - $10-15

Extra razor blades - $5

Printer sticker paper - $15

Electrical Tape - $1

3m double sided foam tape - $4

Heat Shrink - Not sure, maybe $5 new for the assorted kit?

I think that's all of it, I'll update if I think of anything else.

You need connectors like this or you could get a bunch.
