Absolutely, hi-vis is the first thing to do. I never said to get a bright light and not do anything else. Just because I want a big light, please don't assume that means that I think it will automatically replace all other safety measures, as this is a silly assumption.

I wear a hi-vis vest, I have a lot of reflective tape on my bike, I have reflectors in my wheels, on my bags, on my ankles. I'm also running a DesignShine DS500 on the back and an Axiom Pulse 60 on my helmet, and a 400+ lumen light up front. I'm thinking about going with side lights too (lesser taillights pointing to the sides), and before I go to the really dangerous commute in early 2016, I intend to have a high pole with active lighting on that as well (it's likely to be too high for reflectors to be effective).
