I have one of those expensive LED tail lights which has a circuit board with about 80 LEDs and some diodes and resistors , about 18 of the LEDs are not working even though the circuit seems complete and all the resisters and diodes test OK ,i have a multimeter and do basic electronic testing ,There are no dry joints either , How can i get this thing fixed it cost over $100

Perhaps some of the LED's are for park light function and the rest for brakes?
Broken track on the board?

Sorry I can't help any more, unless I can have a look myself...good luck!
