The "Service Engine Soon" light is Ford's check engine light (or malfunction indicator lamp - MIL lamp). Did a shop replace the timing belt for you in the last couple days? The SES light can come on for any number of reasons related to emissions faults so I suggest calling the shop and scheduling a time to take the car back. Some faults take a couple days to appear because the computer needs to see the fault (problem) for more than one "drive cycle".

Do you have any drivability problems? In other words, does it seem down on power, hesitating, bucking, etc? It may be something simple like a connector wasn't completely secured but the shop should scan the computer for the trouble code and determine the cause for the light. hope this helps!
