It's a very simple process to change them out. The user's manual points to the steps to replacing them.
However, finding LED's which don't throw off errors can be slightly difficult (adding resistor packs). I recently changed my halogen turn signals out for LED's, but I also had my car coded to turn off hot/cold monitoring of the LEDs in order to avoid errors (I didn't want to deal with adding resistor packs). I figured with LEDs they shouldn't die out.
Check this thread out:
Anyone here done LED front turn signals?
I purchased those exact same LEDs dmclaren used.
