What are these electronic parts for? Answered
I was taking apart this toy car called a formula fueler from hot wheels and found these to parts that look like leds but on a board. They each have a led thing and two wires on has red and black wires while the other has purple and black wires. The red and black one has thes letters on it "LED REV:03 B4048-0030050" and the one with purple and black has "PHO-TR REV:00 C4331-003-5000". What are these and what are they used for? Should i keep them for future projects?
