They are illegal. I still love mine.

Lens Covers (Blackouts) State law Sec. 547.3215 incorporates Federal Motor Vehicle Safety Standards, Subpart B, Federal Motor Vehicle Safety Standards, Section 571.108, Standard No. 108; Lamps, Reflective Devices, and Associated Equipment. This standard contains the following:

• S5.1.3 No additional lamp, reflective device or other motor vehicle equipment shall be installed that impairs the effectiveness of lighting equipment required by this standard.

As a general comment, any device that impairs the required effectiveness of headlamps, taillamps, reflectors, etc is prohibited. The lights, both front and rear, are made by the manufacturer to meet this safety standard. An alternate or additional material, particularly something dark, would impair its effectiveness.
