I have a single-tube fluorescent light fixture that I would like to convert to LED. However, the wiring is a bit odd.
The left tombstone has two white wires (in one socket) and one blue wire in the other socket. One of the white wires is the white wire to the ballast and the other white wire is connected to the white supply wire. The blue wire is the blue wire to the ballast.
The right tombstone has two red wires (one in each socket) and they lead to the other side of the ballast.
The black supply wire is connected to the black wire to the ballast. The ballast has the black, white and blue wires on one side and the two red wires on the other side.
How do I re-wire to bypass the ballast and convert for a two-sided led tube? Currently, the fluorescent bulb is a single T12?
Any help is appreciated. Thanks.

There are loads of questions with answers on this site that address this question and loads of YouTube tutorials on how to do it.
I prefer to remove the ballast, its wiring and the tombstones.
Replace the tombstones with Non-shunted ones and wire directly to one tombstone. Use wire nuts to pigtail 18awg wire to your black and white ( line and neutral ) house wiring and wire them to the two wire inputs on the non shunted tombstone. ( ground to the metal fixtures body. )
Use a direct wire or ballast bypass led tube.
I do not see the point in powering a ballast if it is not needed other than for people who are not comfortable making the electrical changes. ( its a waste of power )
