I took apart an old bike light I found for my labeling assignment. It had 3 LEDs, 6 resistors of various resistance, 2 capacitors and 3 transistors. I pulled up the datasheets on the Transistors by typing their numerical names into google. I also used this handy webpage http://www.kpsec.freeuk.com/components/resist.htm to look up the values of the resistors by color bands. Also, because the light runs on two 1.5v AA batteries in Series, i deduced that the light requires 3v to operate properly.
