My right side registration plate light has been causing me some trouble over the last few months.
I have the led's installed and no problem for a whole year. Then the one on the right allowed some water ingress and it shorted.
I cleaned it all up and put a new bulb in.
Rubber seal looks intact and it's screwed tight so I don't imagine water ingress is coming from the bottom but another lights has now failed.
Any thoughts?
