During landing with light snow and no braking action advisories on ATIS. Captain slowed aircraft to make the high speed turn off. Aircraft started to turn and then began slipping on the snow/ice at the turn off. Captain regained directional control and made the turn. We did not feel anything unusual; but thought it was possible that the right gear could have contacted a taxi light during the skid. We notified Tower of the deteriorating braking action and contacted Ground to request an OPS vehicle inspect the lights. OPS reported that lights were not contacted and no excursions or problems noted. We then continued a normal taxi to the gate; using caution due to the conditions. Crew was not alerted to deteriorating conditions.
No braking action advisories or runway reports ATIS prior to the final approach fix; aircraft were being vectored off and back on to the localizer (including us) due to the tight spacing between aircraft. Landing and touchdown normal. Part way into turn for the taxiway to my surprise the aircraft started to slide on ice and snow with some control with steering and differential braking.
B757-200 slid sideways onto snow while exiting the runway after landing.
