This mount lets you install LED strips INSIDE your Sailrite sewing machine. I hate external lights. I wanted a downward spread of lights.
Requires LED strip lights. I got the simple 12v white strip lights sticky back available anywhere. They are all the same.
I used super glue to tack the ends to keep them from coming off.
3mm screws through the side plate into nuts into the slider for adjustment.

Also I installed 2 LEDs shown to give me light from the right side of the needle. They are EDGELEC 30pcs 12 Volt 5mm White LED Lights Emitting Diodes Pre Wired 7.9 inch DC 12v LED Light Clear Lens Small LED Lamps.
Drill 5mm hole through casting at an angle towards the needle. Hot glue in place with wires.

Everything wired to a simple toggle switch.
