If you're sure you won't be caught in the dark, why bother with a front light? It wouldn't be visible, unless it's one of the super-expensive kind. As for a flashing rear light, I always used the VistaLite and have had people tell me they really noticed it as they drove behind me. The batteries last a long time (years). I used to commute quite a bit in dusk and dark, and VistaLites saw me through approx. 10,000 city miles. You're supposed to have a rear reflector in addition to the light, though I never did. When turned off, a VistaLite has fairly good reflective quality.
