Weller D550 soldering tool LED Mod

This old Weller D550 has 2 of the same bulbs as the 8200 but they are wired in series. That means there is enough voltage to operate white LEDS which need around 3 volts. I used 4 leds for this and used my component tester to match the forward voltages to get even brightness.
