I rode tonight on my commute. Strobing white LED in the front (I can see the strobe light reflecting from signs a hundred yards off or more), 300 lumen Terralux tactical flashlight fixed to my front rack as a headlight, a PDW Danger Zone tail light on zzzzZap mode in the back, and a rear facing red helmet blinky running in solid mode. I was wearing a hi-viz chrome yellow wind shell. I saw a couple of other commuters, also lit up in a similar fashion. That PDW tail light is visible from quite a ways off. Come to think of it, my MKS RMX pedals have front and rear reflectors on them.
