Turn Signals: The orange tint in the upper, outer corners? No orange tint there except on the lightbulbs according to some other threads.
Fog Lights: The fog lights on other countries models are inverted L shaped for a reason. Those countries have requirements on side-facing lights for illuminating side roads/entrances while turning in to them. There are also two light bulbs in each foglight assembly. Essentially, they illuminate the side road when you have your turn indicator on. I would like to see a US swapout mod.
Skid plate: Probably doesn't fit because there is a different front (and rear) trim for UK/euro/africa vs US. I have noticed that all the euro models use the same lower trim (rocker panel) regardless of engine spec. Euro people, please carefully examine pictures of US EX, LX, or base models vs the SX and notice that the lower trim (all black plastic) is quite different. I find that the non-SX trim (which may be same as in euro models) has a roundness that makes the whole car seem separated from the ground, whereas the us SX trim is back curved to make it seem like it is flush/tangent with the ground (except for the 8 inches of separation). Sorry this is hard to describe, but quite apparent to those that are aware of it.
Some US models do not have the DRL led's, the base model and std configuration of the LX (DRL are an option for the LX). I believe that the DRL in the US vs UK run differently. Both switch off when turn signal is used, but i think the DRL in UK are brighter when the headlights are on vs US. I might be wrong about this, though.
My (OEM) hood deflector is screwed into my "bonnet" or hood. It is attached to little steel hangers, that are in turn self-tapping screwed into factory indicated (via punch indentation) positions. My vehicle came pre-equipped with it and i am not a big fan generally, but i do like the way it helps break up the front end and darken it to let chrome pop more.
My hope is that KIA or someone begins selling some additional accessories and trim pieces. Perhaps as new models come out that are based on the same body/trim, we will see some additional factory accessories. My fingers are crossed for HID's, low-profile aero-style crossbars, skid plates, metal-look pedal and footrest covers, and maybe some flashy bits of chrome trim for the interior (HUD, gearshift base).
