For a constant draw, a resistor will work fine without the zener. But, hey, if you like parts, an LM7806 regulator IC will give you rock-solid voltage regulation that'll make your light bulb the happiest little light bulb that ever illuminated a gas gage. And, it even has its very own zener diode inside it.
