This thread has hit on one of my pet peeves. Yes, I'm a light geek, I admit it.
That said, jon c. has said it best. Your advice would not be well received at all.
Best hope is that a LEO spots them. Enforcing the law is the police department's job.
Having said all that:
1. Why on earth would anyone ride without lights today, given how fantastic today's bike lights are?
There is simply no defense or excuse for this.
2. As someone mentioned, you can't fix stupid.
