A line inspector reports about a B717 that required an air turnback for a nose gear light that would not go out after pilot placed the gear handle in the 'up' position. After numerous successful gear swings and no fault codes noted in the aircraft's mcdu; inspector suspects the ramp crew that performed the push-back may not have noticed a nose gear pin still installed.

Narrative:
June 2010; I was at the line maintenance office. The maintenance supervisor advised me that a B717 was on its way with a nose gear problem. I was asked 'do I need to rii a nose gear swing?' I said not if you don't rig; adjust or change anything. [Landing gear] jack and tools [were] in place awaiting aircraft to arrive. Upon arrival; mechanic talked to crew and it was decided to jack the nose gear and to do a gear swing. Mechanic 'X' and I watched the gear swing three or four times; heard nothing; nor saw anything abnormal. Lead mechanic said swing the gear five or six more times to make sure; still no problem. Lead mechanic said do you have to rii this and I said no; but that I would anyway just in case the crew wanted a 'second set of eyes.'lead mechanic and myself went into cockpit to see if it had any previous fault codes or history; none were found. We down-jacked the aircraft; took the tools away; and I waited in the line office for lead mechanic to come sign the logbook; and we did. The item was not a rii; I should not have signed the logbook; I thought the crew would feel more comfortable if there was a 'second set of eyes' watching the gear swing.I don't know [how] the circuit breaker got missed; possibly the breaker was pulled to stop the aural warning while we were checking for fault codes.
