Did wonder about getting a sheet of the same foam material that they make the seals out of, but I don't know exactly what the stuff's called as there's many different types of foam available.
Hadn't thought to look at the two other locations so we'll give them a try
I had the same problem and took ages to sus it out.
Where the light screws to the body there is a grommet that has a foam back that push fits into rear quarter. They Persish. Mine was a 52 plate car and happened when it wasn't even two years old.
I ordered new ones. Ang guess what they had changed the foam to a rubber.
If you want a cheap fix take them out and seal back in with mastic.
