Review on NEW SUN Trailer Connector Electric by Vincent Burton

I bought this tester to save time and quickly test my 7 pin trailer connectors in my rigs. two LEDs do not work. The left signal is very weak, the blinking light is almost on, the right signal is dead. I carefully removed the LED head to reveal the circuit board. There is continuity between the pins and the solder joints, so the problem is either with the PCB wiring to the LEDs or with the LEDs themselves. Since everything is formed, let's just call it dead. I'm giving one star for the glowing LEDs.
