Step 4 Drill holes for LEDs

While the wires are off to one side prepare to drill holes for the LEDs. Since the LEDs are 5mm you want to measure 2.5mm from the lip of the case as an easy way to keep things centered. Mark that with a knife or pen. See photos for details.

Then use a marker to decide where the three LEDs should go. I started with one closest to the wires and then spaced my other two about 10-12mm apart. You dont have to be super accurate but it will help for installation if they are evenly spaced.

Drilling Tip! Use a smaller drill bit at first to create a pilot hole because it is easier to keep steady and more precise. This smaller hole will also help keep the larger drill bit from walking�� which means your hole might not end up where you thought it would.

Try to keep your drill perpendicular to the surface so the LEDs will stick straight out from the body and not at different angles. (For wider illumination coverage you can purposely angle the left and right LEDs toward the outer edges but it makes assembly a bit trickier.) You also dont want your LED too close to your mounting screw.

NOTE: if you used a 5mm or #9 drill bit the LEDs probably fit fine. But if you only have 3/16" available it will be a very tight fit. You might have to work the drill bit around to grow the hole diameter. This is not the proper way to use a drill, but you do what you can.
