There's very little if anything I can add to what everyone has said repeatedly.
You need a pair of good front lights, a handlebar light with about 1,200 lumens or so, though typically you won't need more than 800 lumens unless you have difficulty seeing in the dark, but the extra is in case of rain, if possible find a light with aimed optics; the second light needs to be on the helmet, about 800 lumens running at 400 or so, with a helmet light you can move your head and light up whatever you look at including cars at intersections.
Taillights, one on the helmet and one on the seat bag or seat post, each running at around 250 lumens, one on steady and the other on strobe or flash if where you live it's legal to use a flashing rear light, if not steady is fine.
Then of course you should wear a reflective safety vest, reflective tape added to the helmet, and a reflective leg bands.
