Our 2 fluorescent bar lights in the kitchen burned out after 4 years
so I replaced them w/ new bar lights.
I must not have replaced them correctly as we see it takes
a bit longer for them to light up and several days ago, it would
light up dimly occasionally. Since then, I took them out
and put them back on, and now, they light up although it takes
longer than the original bar lights.
The question is: These bar lights have 2 prongs at both ends.
I slide them into the fixture, but how do I know it's locked in
Sorry for the newbie question.
