2020 Led light.

Used the cheap 27w led that has a current drain of 1 to 1.5 amps on 12v - halve the amperage for 24v

The thinner housing is usually the lower amperage - if you look at the height of the housing.

Rocker switch used is this type shown in the picture.

The slides are attached to a 5mm flat bar attached to a wall. I use a 1 meter extrusion - was slightly twisted on arrival - so the flat bar will need to be similar length.  Depending on length and weight you may need 3 or more slides.

Printed in abs.  Used tree supports.  20% infill - depending on your intended use.

M6 x 16mm bolts / washers - preferably stainless steel.

Depending on led make, I would not use these for automotive use - the lenses discolor in the sun or fall out.   Rather get a branded name.
