Reason for today’s visit was to assess power loss to the front lights as well as a flickering light in the hallway bathroom exhaust fan light. After initial inspection I found that there was a Old extension piece screwed into the fixture before the bulb that had failed. I remove the extension and screwed the bulb right into the fixture and the light worked properly. After assessing the hallway exhaust fan light fixture I found no wiring or connection issues or voltage loss issues. Yes you appears to be the fixture itself that plugs in that could be going bad. I would recommend ordering a new one to avoid future Strobing of light. While on site I noticed many of the devices in the original part of the house were the original ones to win the home was built. These receptacles were still the two prong style and should be replaced customer went around and got a count of how many switches and plugs that were still original and gave them to me so I can provide an estimate for a future replace
