I modified a spool holder STL to support an angled LED strip that is usb powered and remote controllable. I can post the STL if anybody wants to print this and below is a link to the LED strip on amazon.

LED TV Backlight,SMY USB LED Strip Light,RGB Multi-Colour LED Light Strip Kit Waterproof IP65, 30LED with Wireless Remote Controller for TV/PC/Laptop Bias Lighting (3.28Ft)https://www.amazon.com/gp/product/B075VSJTR9/

I ended up cutting the LED strip to fit my Ender3Pro (13 inches) but you can use this for your printer as your sizes may vary. The LED is connected to the OctoPi controlling the camera and prints under the faceplate.

And, yes, my cable management is shameful...for the moment.

Edit: STL for the lightbar is now up on thingiverse https://www.thingiverse.com/thing:4773863
