We carry Vivid black color spoiler only, they can't be mounted conjunctional with the top rack.
Q & A:
Q: Is this a typographical error (i.e. can it be installed where one already HAS a trunk rack?)
A: This spoiler can't be installed for our trunks (only) with the top rack. It can be installed if you have a top rack which has enough clearance.
Q: Can the spoiler lights be wired as a brake light AND a running light?
A: This spoiler only can be wired as the running light OR the brake light, can't do both.
Q: Once installed, what is the height of the spoiler from it's uppermost (rearward facing) point to the surface of the trunk lid?
A: The height is 2.5 inches from the face of the lid to top of the spoiler
Q: Your ad mentions optional flashing lights. Can you explain/describe this?
A: The Flashing light is build in with the spoiler. A buyer can choose either solid brake lights OR flashing Brake light, depends how you do the wiring.
