Get the webelectric sequentials! They are great and all the questions you have can be answered by them. I have them on the 06 and they light up from the inner aspect of each taillight first when braking on both sides and then which ever turn signal is on continues to blink from the inner to the outer part of the individual tailight being used for turning! If you put the hazards on they both continually light up in sequence from inner to outer and reminds me of an emergency vehicle that has his lights on! Really cool effect and I have had many compliments on them!
