Check the figure below to make sure you have selected infrared LEDs and not
phototransistors. The infrared LED has a taller and more rounded plastic dome,
and is shown on the right side of this drawing.
Assemble the IR Headlights
Insert the infrared LED into the LED standoff base (the larger of the two pieces)
as shown below. The standoff is shaped to fit the flat side of the LED.
Make sure the IR LED snaps into the LED standoff.
Slip the short tube over the IR LED’s clear plastic case. The ring on one end of the
tube should fit right into the LED standoff with a little twist.
