TEXT:

We have received your letter of January 28, 1993, asking whether you must disconnect an original equipment center highmounted stop lamp when you add an aftermarket spoiler to the deck lid that incorporates such a lamp.

I enclose a copy of an interpretive letter we sent David Holscher on August 31, 1990, which remains our position today. In brief, a spoiler lamp will supersede the original equipment center lamp. When the spoiler is installed, Federal law does not dictate whether the original lamp must be disconnected or remain usable. That question is answerable under State law, and we suggest that you consult the Department of California Highway Patrol for its views. If California has no regulation bearing on this problem, we assume that you may either disconnect the original lamp or leave it connected, as your customers desire.
