Narrative: Landed in ZZZ was normal. Visibility was 1/2 mile fog snow RVR 2;400 feet. Runway code was 3/3/3 and the previous landing reported fair braking. We landed flaps 30 auto brake 3. The airplane slowed down normal. Had to roll to the end due to taxiway closures. As we approached the end; I told my First Officer [we] needed to go slow in case it was slick. As we turned off [Runway] XXL the plane started to slide in the turn. Used left engine thrust reverse to help. Hit 3 taxi lights we did not leave the pavement. Taxied to the ramp notified ATC of the situation and was told we hit 3 taxi lights. Called and notified Dispatch and Maintenance Control. Made logbook entry. On walk around no aircraft damaged noted.


Second narrative: After an otherwise normal landing in ZZZ; the aircraft started to slide on a patch of ice as the Captain was turning off the runway and onto the taxiway. Although the aircraft never departed the paved surface; we were uncertain if the slide caused any damage to the taxiway lights. We informed ground control of the slide and the possibility of striking a taxiway light. Ground control notified the airport operations to have them take a look. They reported back that there were indeed 3 taxi lights down. Weather conditions at the time were 1/2 mile visibility with snow and fog. The [Runway] XXL runway condition code was reported as 3/3/3. We landed with auto brake 3 and the aircraft slowed normally. ATC requested a turnoff at the end of the runway due to numerous taxiway closures. It was at the end of the runway while turning off that the aircraft entered into the slide. No damage to the aircraft was found by either the flight crew or Maintenance upon inspection of the aircraft at the ramp.Unfortunately despite the rest of the runway having adequate braking; the runway end was incredibly slick. The only suggestion that could've prevented this would have been to make the turn at an even slower speed in order to possibly prevent the slide.


Synopsis: Air carrier flight crew reported loss of directional control while exiting the runway due to 'incredibly slick' conditions.
