Really, any 5mm bright white LED could be used. I like the one listed below because it is much brighter than any other LED light I've used. Check the voltages of the LED you use, if the LED is rated for less that 3.2V, reassess which resistor you put into the circuit.

Probably the trickiest part to source. Below are several links to lenses that would work with the otoscope. Following the video tutorial, you should manipulate the lens to fit in the holder. I recommend also checking local department stores for these items too. They can go by the name of "pocket reader", "3x magnifier with LED", and "Easy reader".
