Is there a reason for the anvil and post in a LED having the shape they do – other than making it easier to distinguish between the anode and cathode?

Best Answer
Both wires are placed symmetrically with respect to the LED's axis. The die is also placed on the axis. Therefore the cathode wire (which holds the die) has to extend towards the center line.
The anode wire is shaped so that you can't pull it out the plastic housing.
