I designed these holder / fixtures for G4 12VDC LED automobile dome lights: https://amzn.to/2V2rzLL

Print using PETG for best results. I used Hatchbox Orange to match my Prusa i3 Mk2S perfectly. https://amzn.to/34w2CN1

and Overture Black for some other applications.

The retainer ring snaps into place firmly holding the LED inside. Solder the wire leads before snapping the ring in place. The ring is removable, it just makes assembly that much easier. You can use my photos for wiring reference. They should be wired in parallel and powered by a 12VDC output source. Remember, the more you string together the higher the amperage power supply will be required or the light output will be reduced.

I use these to light my printers and work area, but they will work nicely for under cabinets, inside cabinets, behind entertainment centres or anywhere you want bright economical lighting options.
