Due to <circumstances>, the third brake light (*) on our 2019 Forester Limited got cracked. The light still works and a piece of clear tape covers the hole nicely, but the dealer pointed out that the car will probably fail the next safety inspection. The part costs around $100 but the dealer wants $200-ish to replace it - I assume they're charging for about an hour of work. How hard would it be to replace the assembly myself? This model has the rear spoiler so I'm thinking some amount of disassembly and reassembly would be required.
(*) also called the "high mount lamp".
