The only puddle I don't care for around the zoo right now is the one under the new pedestrian bridge. Deep in the middle so I slow right down and go along the south side to stay on the harder ice. Lots of bell ringing before in case someone is coming the opposite direction.
As for rear lights, I have a couple of those cheaper USB chargeable Lezyne ones, think they still have them at Ridley's:
