The light locations are stock, but someone may have decided to install something other than stock bulbs or other related parts in the factory location. I have to admit that the stock lights are a bit dim and I've thought about modifying them as well.

I have heard something about those lights having been lifted from another type of vehicle and incorporated into the VX design by Isuzu, but I'm not totally sure that is the case, and at the moment I do not know if those light components are from any other manufacturer than Isuzu.

Lots of cars have subassemblies made by other manufacturers. I was recently told Isuzu parts are in some Mitsubishis and that there is a lot of mixing of the blood, so to speak, in Japanese automobiles. And otherwise - the V6 Dodge Avenger I used to have was all Mitsubishi under the sheet metal and was built in the same factory as the Eclipses. The dash looked like that of my brother's Eclipse. The engine was a Mitsubishi one, and almost all of the mechanical stuff and chassis were borrowed from the Mitsubishi Galant.
