What bulb can I use to replace the lowest bulb on the headlights...the one that is on when you don't fully have the lights on. It shines that crappy yellow color and I would like white or blue.

 

Check your local MVC codes - I know that blue is a prohibited color here and it's likely a federal law. The CA motor vehicle code allows white and amber forward. The Florida one is likely on line as well. It's always your choice buy my wise old mother told me to never invite the po-po into your life.

 

I replaced mine with a silver coated bulb but it gives off very little light. I wasn't looking for it to be bright though, i never use my parking lights, i just wanted to get rid of that yellowish color.

edit: this is where i got them: http://superlumination.com/194.htm scroll to the bottom to incandescent bulbs. I didn't use LEDs b/c of their tendency to burn out in the hot headlight housing.

 

it's a 194 or equivalent bulb--I replaced mine with an LED substitute that's pretty similar in color to my 6000K HID's. They've been good so far, no burning out and Mr. Zipps (who sold them to me) says he's never had any customer complaints from them failing.

 

I've got a LED running lights as well (not because I think its baller, just because one of my OEM's burnt out), and they work fine so far. They are 194 "wedge" bulbs. You can find them all over the net and probably locally as well.
