VW Jetta 2006, Quick question

Both my taillights went out at same time. Consequently it was right after i received an oil change. Could they have knocked something loose? Or do you think it was just a fuse or circuit board short? Thanks

Hi there. I would check the fuses and the bulbs themselves. I guess it's possible they did something to cause that, probably not though. Maybe both bulbs just decided to quit at the same time.
