Leaking gaskets around the tail lights can allow water entry into the tail light assembly. New gaskets should fix this concern.

Passenger side tail light leaks water into trunk especially after it rains. Prior posts say replacing gasket does not work. No problem with driver side tail light.

I have the same problem. Water getting into the Passenger Tail Light and leaking into truck. Now, my taillight is filled with mold. I am thinking with all the people that have reported this problem, Honda should have had a recall on this part. Hope to get my fixed or replaced soon, at my own expense.

My 2001 Honda Accord (74,000 mi) has the same problem. Passenger side trunk mounted light collects water and spills out inside the trunk when trunk is opened.

Trunk-lid-mounted tail light assemblies fill with water to a depth of 1-1/2 inch in wet weather. Water pours into trunk when lid is opened. Trunk is wet. Spare wheel well is half-full of water. Replaced foam rubber gaskets between tail light assemblies and trunk lid, but this had no effect. I can't see where the water is getting in.
