Pros
- Primetime racing improves television ratings
- Rain date is more fan and television friendly
- Easier travel arrangements for fans
- Less traffic
- NASCAR is more vivid, intense and exciting under the lights
Cons
- Directly conflicts with local Saturday night short-track racing
- Expensive for tracks to install lights
- Some months and/or locations would bring cold weather after dark
- After a brief shower there is no sun to help dry the track
Where it Stands
Currently Atlanta and Texas are both equipped to run NEXTEL Cup races under the lights but run both of their races in the daytime. Those would be minor schedule adjustments.
I am not aware of any additional tracks adding lights at the moment. Martinsville, Dover and Michigan would all be good candidates for lighting systems, but at the current time there is no incentive for them to spend the money.
