First responder is completely wrong. The actual story is this: neon and fluorescent lights rely on having a low internal pressure, because the gas in them is more conductive at low pressures. Technically, the mean free path of a molecule of gas needs to be long enough that it can obtain enough energy from the electrostatic field to ionize. The lamps now being used in high-intensity-discharge auto headlamps, however, work on a completely different principle, and the gas pressure in them is fairly high.

No. At high pressure the current is opposed and none flows, leading to no light passing as the gas molecules collide with the e-'s.

pressure INSIDE the lights when turned on must be the same or lower than the OUTSIDE atmosphere, otherwise the pressure will make the lights explode.

Not fluorescent tubes, only Neon signs

Discharge lamps can be high or low pressure.
Neon lamps & fluorescent tubes are 'low' pressure as are SOX lamps (low pressure sodium).
SON (high pressure sodium), MBF(mercury) , MBI (metal halide)lamps are 'high' pressure.

Any gas can be presureised. will the gas glow hotter or burn brighter? yes

nope it will explode
