For the LED's, make sure you read up on their draw backs and requirements as they may not work as expected if you get the wrong bulb. For the turn signals, it looks like you have to have a "dummy" load to create the extra current load that the flasher relay requires to work properly, for instance. Also, the light from an LED has a much tighter wave length than an incandescent bulb, so a white LED will not work well in a red tail light lens. There isn't enough "red" from the white LED to get through the red lens. (or something like that!)
