Dinotte 800L up front, PlanetBike Superflash in the back (typically in "blaze" or steady mode because I think it's easier to judge distances with a steady light). I don't want to overdo it on the lights. I want it bright enough to see and be seen, but not so flashy that I confuse drivers behind me. I also wear reflective ankle bands and a reflective vest. I believe this helps drivers instantly recognize me as a cyclist as opposed to a faster vehicle like a scooter which they may approach more slowly.
