I havent really seen this done yet but have seen some discovery's without lower tail lights so i assume its been done.

 

03-04 came this way. You could get those housings and re-wire. Another option is to get a trailer harness adapter and combine the brakes and turn signals, so they work like old crappy American cars. Another option would be to get yellow bulbs for the revers lights and wires those as yur turn signals.

 

I switched my turn indicator wires with the upper turn signal, added amber bulbs and then wired in a Hella work light to the licence plate housing with a 100 watt bul and it works great.
