Narrative:
During the climb; we encountered icing conditions. We noticed immediately that the #2 engine air inlet light did not come on. I recycled the switch and then switched the override knob to 'on' as per the QRH. The light turned on momentarily then went off again. After exiting icing conditions we proceeded to our destination (all ground below was under a cloud layer). We continued to trouble shoot during the flight while attempting to contact maintenance via ACARS and a commercial radio link. Once getting maintenance we determined that the valve was most likely stuck. We informed dispatch of our fuel and asked for a possible alternate to avoid icing. We also asked ATC about a nearby airport that was not IMC and asked for icing reports for each. Once it was determined that avoiding icing was impossible for landing; we declared an emergency. We briefed the flight attendant and the passengers of our intent to declare an emergency just as a precaution. After exiting icing conditions (on the approach) and determining that the runway was free of contamination we quickly notified the flight attendant and tower that we would have a normal landing. During icing conditions in the descent the inlet light was intermittent.
