A 555 circuit switching an SCR can do it. That plasma is pulsing off and on, but for the most part, it does exist almost constantly since the turn off time is maybe not enough for it to fully decay.

There are advantages to my plasma method but a simpler way is to simply put a cap across the gap with the diode and its own power supply. You can then use a normal ignition discharge to trigger it.
