Lights only matter if you ride at night.
I run lights in the daytime too, for better visibility/awareness to others, and get compliments for being easy to notice. Even the "real" road bike gets DRLs (its predecessor was destroyed by a left-hook by someone who didn't see me).
I dislike the bike industry's sweeping "commuter" presumptions. If I had to commute with the industry's prevailing idea of a "commuter" bike, using "commuter"-level lights, I'd be pretty frustrated.
