Usually there is no room to put an incandescent light bulb in series
with a cathode to ground, and then it needs to be a high voltage rated
type; it is a primitive non-solution, and ppl cannot buy old fashioned
light bulbs in Oz now because they have been deemed to be greenhouse
incorrect and the only globes are now compact flurescent types.

Surely you can buy the small panel lamps and automotive bulbs? We are
not talking 100 watt house bulbs but small stuff. I won't allow CF in
my house due to the mercury. There will always be some niche source
like Avgas for tetraethyl lead.
