you Are right its not , i just wanted to prove that it worked , the RHS is a single filament bulb as well , it just makes it brighter , both are single filament

Thanks , for all your suggestions . The n/s bottom lamp is a side light and fog light , the fog light works but not for side light . is there some coding i need to do so it knows it should be a side light

nta16 thank you for your reply. No LEDs , live and earth are getting to the holder , bulb is ok but does not illuminate

Evening all help needed please my N/S bottom part of the C lamp does not work , I have checked the bulb , I have even swapped the holder from left to right but still the same. 14 plate mk3 2.0 Tdi Elegance
