I wanted to change up all the ugly stock bulbs so I looked at the kits that were available on the forum and online. No way am I paying $40-80 for LEDs when I know they cost pennies to make. All these vendors are heavily marking up the prices, charging you $80 bucks for something they made for less than a couple bucks.
I found a $20 shipped kit from Fyreflys. It works flawlessly and looks just like everyone else's pictures. Granted it's not nearly as bright as the $40 dome light kit sold on zstore.com but I don't need a light show in the car either.

For the daytime running lights and vanity light, I looked on ebay and found these:
13 SMD LED Car Light Bulb Xenon White for Tail Brake Backup Wedge Lamp T20 5050 | eBay
This same one sells on VLEDS for $8 plus shipping, compared to $4 shipped
1x36mm Super White 3-SMD 5050 LED Bulb Reading Lamp HID Xenon Festoon Dome Light | eBay
$2 shipped vs ijdmtoy.com $8 plus shipping
I could've probably found the dome light, trunk light, and tag light that's in the Fyreflys kit on ebay as well for about $10-12 bucks as well but I didn't think to look on ebay first.
They work perfectly. Don't spend $40 for a pair of LEDs unless you actually need the inside of your car to look like its daytime at night.
