My rear Parking Lights have stopped working (Indicators, Boot Fog Light, Number Plate Lights & Brake Light are working perfect). Problem began when I removed the rear bumper to fit a rear lip (Removing the rear lights and bulbs in the process). I checked the 10Amp fuse in drivers footwell and it's not broken, swapped the Brake bulb to the Parking Light connection and it won't work even tried a whole new connection from a Lexus I have here for parts and still won't work..? It's both rear lights in question so I'm assuming it's a fuse/relay ect..? Any info or help greatly appreciated..
