9.3.32. LIGHTS
All non-Formula cars shall have two operating red brake lights. All For- mula (open wheel) and Sports Racing cars shall be equipped with a red taillight of at least the equivalent illumination power of a 15 watt bulb. This light shall be mounted as high as possible on the centerline of the car and be clearly visible from the rear. The taillight shall be illuminated when ordered by the Chief Steward. Light assemblies shall be considered one light for the purposes of this rule, irrespective of the number of individual lamps the assembly may contain. Light assemblies may perform both rain and brake light functions provided they have two distinct illumination lev- els. An optional tail light (“rain lightâ€), as described above, may be added to cars in all other classes.
Exposed glass headlights shall be taped. Rear brake lights may be tape- dwith transparent tape. Turn signals, front parking lights, backup lamps, and side marker lights may be taped or painted. Lights mounted on or below the bumper shall be removed, and all resulting holes shall be cov- ered to prevent air passage through said holes. Lights mounted within the bumper may be removed or covered and any resulting holes shall be covered to prevent air passage through said holes.
