Buy lamps from Europe. They come red on the basest of base wagons. They may be possible to get form teh dealer but im sure youd pay an arm and a leg for em. Go to the regional forums and go to one of the european guys and see if theyll pick some up for ya.
i saw someone who used vinyl red overlays that they stretched the over the stock tails. it looks factory made. using a hair dryer and some forearm strength it came out very nice. its in this forum under appearance. check it out. he even tells you how to.
