A couple of weeks ago I was changing a headlight bulb when I lost a small rigid piece of metal that holds the bulb in place (it’s a long and stupid story involving wasps, I won’t get into it). I tried to hold it in place with the handyman’s secret weapon, duct tape. That held for a bit but eventually melted. Plan B was to rip off a piece of coat hanger and jam it in there. Voila! Worked perfectly. I’ll still be taking duct tape along, but I might throw in a coat hanger or two as well.
