My planned lighting setup:

- MagicShine as front
- Terralux 2 x AA on helmet as a spot and backup light if needed
(Backup AA rechargeables in the backpack)

- Mars 3.0 on backpack
- Mars 3.0 mounted on bike rear facing

And
- Reflective tires

And
- BanjoBros backpack. I love this pack because it has 2 ENORMOUS reflective stripes painted down the back. There is absolutely no way you can miss these stripes after dark - I suspect they'll be more effective than the Mars lights once cars are within headlamp range. Still, the MARS will be useful for those who forget to turn their lamps on.

Am still considering a reflective jacket or hi-viz neon yellow jacket, but I don't consider it essential with all this stuff.
