Taillights are a subtle and relatively cheap mod that makes a big difference in my opinion. At a little over $300 with harness and bulbs included for all-OEM upgrade parts these are a pretty easy decision IMO. They are incredibly easy to install as well.
1. pop off the partial shroud of the targa holders and remove the two screws holding the holders to the body.
2. remove the screws holding the rear trunk trim piece in place and remove the trim all together
3. two screws hold each taillight in place, once removed be careful not to scratch the paint when removing them, takes a bit of wiggling, painters tape on the bumper may be a good precaution
4. unplug the harness and pull it out of the body pass-through by compressing the grommet seal on the back side until it comes through.
5. assemble the new bulbs/harness/tail lights and re-install in reverse order!
