Narrative:

During taxi from the ramp; we were given instructions to exit our ramp; cross runway 4/22 and make a left turn from taxiway C3 to taxiway C; continuing to hold short of runway 12R. Unbeknownst to us at that time; no other aircraft had used taxiway C for the past 20-30 mins and it had been snowing quite significantly for the entire time; thus accumulating snow on the txwys. As we began our left turn onto taxiway C; although we were quite slow (INS indicated 3 KTS ground speed); the aircraft began to slide towards the outside of the turn. I attempted to stop the aircraft; but to no avail before hitting a blue taxiway light. Our maintenance personnel came out; inspected the aircraft and towed us back to our ramp. We were then de-/anti-iced once again and departed using taxiway D; which runs parallel to taxiway C and had been heavily traveled all evening. The taxi/departure was uneventful from this point. We never departed the paved surface. Supplemental information from acn 682333: taxi speed was less than 3 KTS and taxiway was covered with less than 1 inch of snow. Aircraft slid in the turn due to snow. Right outboard tire took out elevated taxi light.
