Reflective tape: inside the rims, between the spokes so when your wheels rotate they look like a solid reflected surface, on the cranks and pedals. Anything that moves catches the eye faster. I put reflective tape on my shoes and helmet too.

Don't even think of riding without a tail light.

Helmet mounted light is a good back-up as well as useful for getting driver's attention.

Ride in the bike lane or right of lane but taking up a lane will be a dangerous thing when drivers do not have the same line of sight at night as they do during the day. It's harder to judge distance at night.

Carry spare batteries.
