Smoke deflectors, sometimes called "blinkers" in the UK because of their strong resemblance to the blinkers used on horses, and "elephant ears" in US railway slang, are vertical plates attached to each side of the smokebox at the front of a steam locomotive. They are designed to lift smoke away from the locomotive at speed so that the driver has better visibility.
