Burlington, being an "outstation" will not have mechanics from the airline. Cities like this sub-contract to the local fixed base operator. That mechanic basically will get the call from the airline and do exactly as told by them.
Being the first flight of the day, I can tell you from experience, they probably had to call him at home to get him in. Especially on a weekend day. Then he will call the airline's maintenance dept. and they will instruct him to fix it if possible (no parts on the field means no fix) or write it up in the logbook for a fix in the next city or when available and fly that segment if allowed.
One or the other happened as you were able to fly but don't discount the problem just cuz you say it's a light. Lights are what the flight deck guys look at and one not working can be disaster as mentioned in an above post.
I turn it over to the next guy who will probably say this is forseeable and shouldn't have happened.
