B767 flight crew reports momentary loss of steering during 90 degree turn onto parallel taxiway after landing at ORD. Standing water with temperatures near freezing were present at the time. A taxiway light may have been struck.

Narrative

After landing as pilot flying; I transferred control to the Captain. On rollout/deceleration; we both verbally noted some standing water on the runway -- rain was hard and had been in/around the airport area with temperatures at and around freezing. No rain present at the runway or on landing though weather was misty. Exited Runway 10 at intersection M3; then made a right hand 90 degree turn on Taxiway M. Aircraft was at safe/slow taxi speed and under full control. While completing the turn onto Taxiway M; Captain noted that the aircraft was not responding to nosewheel steering and was sliding to the (north) edge of the taxiway. He applied power and some correction and the aircraft moved back to the taxiway centerline and traction was regained. I called to advise Ground Control. I was cut out multiple times by both Ground Control and other aircraft; but finally got through and advised that the taxiway was slippery; apparently had icy areas that were not clearly visible and also that we may have struck a blue taxiway light. Remainder of taxi to gate was uneventful. We made entry into log book for inspection of left main landing gear. Visual inspection on post-flight indicated no damage.
