You can try these. Will work for both brake light and cargo. I did mine week before last and it looks great. No codes generated, and about 8 bucks for a pkg of four.

* Update * My $8 package of these LEDs just started flickering, so they lasted right around 6-7 months... Probably going to go with either SuperBrightLEDs or Diode Dynamics now.
