Hello Chris,

Understood. Thanks. No spare bulb handy but can put a resistor in
series with the bulb.

Switched voltage halving would be more efficient.

A 6 V, 5 A adapter similar to eBay 305207182573 would be even better
but I haven't found one.

Thanks, ... P.

Put a few diodes in series. More diodes and less voltage of about .5 to
..7 volts per diode.
