Aftermarket LED tail-lamps dim

[Rlbart]

Hello brought some led rear lights. Passenger side the taillights don’t work and brake light is dim. Indicator works prefect and drivers side works prefect on all.
Does anyone know what’s wrong?

like that style in the pic

If you`ve had to re-pin the plugs to suit the new lamps, check the pins havent been pushed back inside the plug and not making/poor contact. Check voltages at plugs.

The wiring to the lights is different for factory standard and factory LED units therefore the aftermarket lights often specifically say which they are intended to be used for as a direct replacement, these look like van x lights and they don’t seem to say which they are a direct replacement for. I guess they are probably to exchange with standard lights therefore if you had leds originally you may need to swap the pins round but I guess see what van x say first. Good luck
