I could join the discord and post it there but like... that'd mean being in the discord so instead I'll drop some info here.

As some might know I've been working on a headlight to go into the ELM box. This being an XR compatible controller housing to contain a VESC and other misc components you may want to contain to build your desired board.
A custom headlight is needed because the final iteration of the box isn't compatible with the existing XR headlights. Not getting into that here since my model does support it but I've been doing some work to make something that will fit in the current version and also be possible to use elsewhere.
I'm about ready to send off for a final revision but waiting on parts to be in stock. below is a look at the CAD for the design.
There are 17x 5050 LEDs, RGBW so that they will be bright enough to be useful (more so than the Pint). I tested an earlier version with just RGB since I had those laying around and they worked really well in my prototype housing (early design that wasn't the final version).
The holes for wiring on the ELM box is only 7.5mm x 4.5mm so although the footprint on the PCB has 2x JST-PH 3 pin connectors you won't be able to fit those through the small ELM housing holes so I recommend soldering directly to the holes. JST-ZH would fit but they have a 1amp current limit and that's pushing it close to the draw with just RGB leds.
The need for through-hole is in turn why the LEDs don't go all the way to the edge since having through-holes underneath an LED is a recipe for disaster and I'm not sacrificing safety for a full length of LEDs where those extra 2 will do basically nothing. I take safety EXTREMELY seriously when making stuff others are going to use. I'm not out here making hotglue time bombs >.>
An additional feature is the ability to daisy chain these. I added Digital Out (DO) on the opposite side so you can in theory program the power button off this too or wire the taillight off the DO... whatever you choose I haven't seen the VESC LED app yet but figured the option would be appreciated.
Here's some video of them being tested with only the RGB version of the LED :)
I'm waiting on stock for the RGBW LEDs to come in, then I can send off for these to be pick and placed then sent to me for additional testing like current observations, temp dissipation and fitment in the housing assuming I get one of these fancy CNC versions rather than my ancient 3D printed one from 6 months ago lol.
I did add 4x 1mm holes in the corners in a desperate attempt to have some sensible alternative mounting solution since currently some sort of thermal & non-conductive adhesive will be needed for the ELM box.
Decided to share this now ahead of asking the PCB fab to spin me up a test batch in case some big brain people wanted to chime in before MK1 V2.1 gets made. It has... kinda gone through a number of iterations and versions prior to settling on this.
