Aren't most "12V" automotive lamps really rated for either 13.6 or 
14.4 volts?  I know this is a nit, but I seem to remember that the 
automotive types are slightly different from normal 12.6V "pilot" 
lamps, even when they share the same base.

Festoon bulbs are also found in marine lighting and can be obtained 
in halogen configurations in 12 and 24 volt varieties.

What's the response of the sensor?  IR or something in the visible 
range?  I've seen white-LED replacements, but if it's an IR sensor, 
that probably isn't going to do much good.
