What would cause new headlamp to immediately blow out in 1988 240 DL?

A new headlamp in a 1988 Volvo 240 DL may blow out immediately due to several reasons, such as a faulty or improperly installed bulb, a short circuit in the wiring, or a malfunctioning electrical component like the headlight switch or relay.
