A light is nice, and there are those who are convinced that it's a safety enhancement in the daytime but realistically it's just about pointless during the long days of summer, unless you do intend ride at night.

I'd add a tail light as essential equipment though. If you do get caught at night, number one priority is drivers able to see you coming up from behind.
