Is this both bulbs on that PCB not not working?
Are you getting a feed to the PCB when you turn the side lights on?
Where was the second hand one sourced and was it working one?
yes put new bulbs in yes the side lights are working car bracker they s aid tasted and was working
No i mean - do you get a feed/voltage referance to the connectors at the number plate holder//you should have two spade connectors to that unit..you need to check it gets a feed when you turn on your lights..if not then you have issue somewhere else either earth fault or supply voltage problemwiring...either a blown fuse you'll need to check for..thats under the dash at the passenger side..you need to removed the panel underneath..and you see the fuse board..and fuse map on the cover or handbook..
These panels that hold your number plate bulbs are so common for failing due to there position on the boot lid behind the chrome section sometimes effected by water ingress,..this is causes corrosion of the pcb board itself in regards ***** ***** solder joints and causes either one bulb to go or both and the ecu will display a message or bulb failure..some people actually hard wire the board so something to bear in mind
