Looks like all you need is that bulb.It has a wide-range (11 - 16 V) input so it obviously already has some kind of current limiting in it. As the 3 LEDs are no doubt in series, even if they're using linear regulation it'll still be about 75% efficient in terms of getting power to the LEDs.
Problem solved!
Mmmmm acid bath.

That board...... will drive three one-watt LEDs in series if you're using a 12V source, so you only need one.
