Question:
I installed four diodes on my 2016 Mazda Miata for towing from your kit. The lights work properly however, the right turn signal and brake light is dimmer than the left and I don’t know why any suggestions?

Hey Tom, that's a pretty odd problem to have. It's either the wiring to the diodes isn't attached securely enough or the diode for whatever reason is faulty and causing a voltage drop on the circuit which is then causing the lights to be dimmer. One way to rule this out would be to swap the diodes from side to side on the vehicle and see if that causes the problem to go to other side of the vehicle.
You could also use a multimeter like part # PT89ZR to test for resistance on both diodes to see if the one has more than the other. If so, that one is bad.
