Will this interfere with my rear spoiler?

This light is engineered specifically for hatchbacks with factory spoilers. The profile clears the wing — test-fit before final installation to confirm fitment on your specific car.

Do I need to modify the trunk seal or gasket?

Installation uses factory mounting points, so seal interference is unlikely. If you're swapping from an older incandescent housing, check that the LED unit sits flush before final fastening.

What's the brightness difference between LED and my stock bulb?

LEDs light up instantly and run significantly brighter than incandescent, making your brake signal visible sooner. You'll notice the difference — the LED fires before a traditional bulb even gets warm.
