Lil PZEV said:I don't know about any specific piece to switch out, but look at these:
They are called the RS, same price as ST170's but seems to have the clear (chromed) turn sig, so I'm sure you could drop orange bulbs inside and be good to go.

Awesome 215 Turbo HP and unique body parts define the Focus RS. The Focus RS headlights are similar to the 2002 European headlights but the amber turn signal is deleted by a chromed cap. The kit consists of 2 headlight housings and backplates. Order the set along with the installation kit to convert your harness to 2002 European. LHD Version.
