I have lots of reflectors facing aft - yellow on the pedals, one round red mounted on each seat stay, one round red on my seat bag, and one red on the back of the rack, and some white reflective tape on the rear rack stays. That is all in addition to the rear-facing yellow xenon strobe that is on day or night.

In the front I have a steady white LED light (used at night only), although I'm thinking of getting a new one that would allow for flashing mode as an attention getter for daytime road use.

I also always wear a reflective mesh safety vest, and reflective tape on my helmet that can be seen from all sides.
