I have a pair of PIAA bulbs that I was going to use for my 06 housings, but I never ended up buying the 06 housings. These are basically the bulbs that go in the orange blinker part of the housing. They are clear when off, and light up bright orange when turned on. Here is a detailed description:

"PIAA Mirror Orange 7440 Light Bulbs (19346) - Bulb Type:7440 - Wattage:12v21w - Manufactory Part#: 7440 - Technology: Mirror Orange - Location:Miniature incandesent - Package contain 2 light bulbs Looking for a way to increase the cool-factor of your clear turn signal lenses? PIAA has the answer Mirror Orange 7440 bulbs. When installed in your clear lenses the bulbs are nearly invisible but when illuminated provide a street legal, orange color that is sure to get noticed. PIAA’s new mirror orange bulbs will have your friends asking how’d you do that!"

I bought these for 40 new + tax and shipping. I will sell these for 30 shipped or you can pick it up for 25 bucks if you are in socal.
