Rear tail light cover with built in luggage compartment light. Will it work in my car

[IS300E30]

My car did not come with this feature, even though it's a 1987 with early tail lights.

If I add this cover, is it a plug and play and will simply work with no issues?

Will this compartment luggage light simply turn on when I open my trunk lid and simply turn off automatically when I close my trunk lid?

Will it cause any additional drain to my car battery?

Plug and play. It is not a separate trunk light. The extra window allows the parking light bulb to light up the trunk area as well as the tail light so the light switch must be on for you take advantage of the extra light. It's a great idea. 84-85 models had it...not sure why BMW did away with it.
