Headlight Knob
You will need one LED and one resistor to change your headlight knob color.
1. Take a look at the trim surrounding the headlight knob. Like the headunit trim, it pulls right off. Behind it are two 7mm bolts, remove them.

2. Disconnect the knob switch and dimmer switch from the wiring harnesses, then remove the dimmer switch. It is held on by two tabs on either side...pry them up and slide it out.

3. Now you are looking at the switch, which you will break down into four pieces. There is a clear light refractor, the switch body, the knob itself, and the trim piece that keeps it all together. The knob pulls off and is indexed so that it may only go on one way. If you look near the end of the clear light refractor, you'll see a little push tab holding it in. Push it down and slide the refractor out.

4. Simply turn the headlight switch assembly to remove it from the trim piece. On the switch itself you will see the little bulb which is providing light. Clip it out as best as you can. It is a good idea to scratch up the surface a little bit so the solder has something to stick to, otherwise it breaks off pretty easily. Solder your resistor in front of the anode. Now you have to insert it into the trim piece in such a way that it won't be hit by the light refractor when you put it back in. I put my resistor above, and the LED below. In the end it will look like the below photograph...
5. Now you can reassemble the switch. Slide the switch into the trim piece and turn it back together. Slide the refractor in and make sure it clears the LED. Then add the knob, and it is ready for installation back into the vehicle.
