i would go with 06 tails, since the 03's don't have three separate bulb compartments. but that's just me. i've also bought and sold a set of 03s, a clear set, and now i'm on a set of 06s. so i guess i'm picky.
^^^^^^^^^^^^^^^^and...are those just normal bulbs roger??^^^^^^^^^
I'm using 3 bulbs with the 06 tails, blinkers on the bottom. I switched the reverse and blinker light sockets around as the 99' blinker socket fits directly into the 06' tails reverse hole. Then I cut a hole in the bottom to fit the 99's reverse socket(which is now the blinker socket).
