Fixing a circuit board?

[519.E82]

To start off, I installed LCI blacklines in my car right before winter. They worked perfectly fine all winter no issues. Come summer naturally I give the car a really good wash, clay all that good stuff and I notice condensation on my driver side tail light (faulty seal). Fast forward a month and now the tail light is less than half brightness (very very dim). Just the bars though, break lights reveres, etc all work perfect, just the running bars. What I did notice though is that when It rains or I wash the car, when water gets in the tail light again the running lights work perfectly.

My question is, is there any way to fix the circuit board so that it works when like its wet? Before anyone asks no, its not the board the bulbs plug into its a separate board for the LCI's.

Thanks.

Fill it with water and seal it together so it can't dry out.

Maybe this: https://www.amazon.com/CRC-Urethane-...mal+coat+spray

But you'd also have to waterproof the connections to the circuit board was well, I think.
