Right - I got the non-led number plate bulbs from T8ups as I had issues with the led ones on my A3 previously. Gone to fit them into my A4 Avant today. Fitted the left holder + bulb - changed screw for stainless steel allen screw - applied some black rubber sealant as the rubber seal had started to perish - tested it and all good apart from the fact that the right light now doesn't work with the normal bulb in it. So went to swap that one out and found that previous owner had rounded off the original screw, must have cut out the old holder, fitted a new one and fitted a self tapping screw at an angle to bypass the rounded off screw shaft! On removing it there has been a lot of water ingress as the angled screw isn't allowing the holder to sit straight in the cut-out
Whatever I do here the new holder will need to be stuck in somehow so without replacing the whole black strip I feel the best thing to do would be to bond or glue the new holder in place. So here's the question........
What will last longer (as I won't be able to remove it if stuck in!) an OEM holder with a non-led bulb or the integrated 18 led units that come as part of the holder?
Also what would be the best product to bond it in with please?
Thanks for any advice
