Correct!
But over voltage is the critical factor in here, which causes the lamp to burn out.
The power dissipation goes up very rapidly as per V²/R. hence heat and meltdown of the filament.
The resistance doesn't change (within reason), The amperage only changes because of the increase in voltage.
A lamp at 85% voltage, brightness 53%, Life 1000%
A lamp at 90% voltage, brightness 67%, Life 440%
A lamp at 95% voltage, brightness 83%, Life 210%
A lamp at 100% voltage, brightness 100%, Life 100%
A lamp at 105% voltage, brightness 120%, Life 50%
A lamp at 110% voltage, brightness 145%, Life 28%
A lamp at 120% voltage, brightness 200%, Life 6%

Hope this gives you a bit of an idea re overvoltage on lamps.
For a 12 Volts automotive lamp 13.5 volts is the design voltage for the filament. The 14 volts from the car alternator minus 0.5 volts for wiring drop.
