I would use reflective as my primary and add the lights. The passive reflective tape is always there and requires minimal maintenance...basically keep it clean. Active battery powered lighting is a PITA to keep maintained, I am a firm believer in the KISS principle. The bikes I ride most at night have generator hubs, head lights, tail lights and one PB Superflash mounted on the rear. I use LED lights as much as possible due to their longevity and gentle use of batteries.
