Ecu Module Import Companies Serbia

Can you direct me to manufacturers of lighting components? I am coming to Istanbul soon and would like to visit the lighting stores of Turkish manufacturers, but not traditional products but modern lighting.

I want to obtain a cost breakdown for fiat parts cars, doblo and punto, spare parts auto that provides a detailed breakdown of costs, payment terms, and delivery timelines.

I am interested in manufacturers of passive network (reck, cable, moduls...)
