simulate this circuit &ndash; Schematic created using CircuitLab

When SW1 is closed all the lights turn on.
When SW2 is closed lamp1 turns on but D1 prevents the other lamps from getting power.

The downside is that the lamps will get a slightly different voltage depending which switch has turned them on.
