Technical Info for LED Driver
This is a very efficient driver for the 3 watt star LED bulbs. The input voltage conncts to the pins and the wires connect to the LED red to anode and white to cathode. It is a constant current supply which puts out 600 milliamps. This driver runs in switching mode at about 250 Khz, so there is some noise. Just connect a 4.7 uF Tantalum capacitor across the output and that will quiet things down.

I purchased a number of these to use with the 3W LED. They work great, but for my application, automotive tail lights, they produce a lot of hash/RF noise through the car stereo when they are on. They work great for brake lights and turn signals, but are noisy when on.

Efficient but not necesssary
I put a 50-ohm resistor in series and limited the current though a LED-248 to 200mA at 14vdc without using one of these. Not efficient (10 watts in the resistor) but cheap and quiet.
