Omega's piaa w-2s really look close to hid color and are pretty bright for being rated at 18 watts. I haven't seen anything comparable. They really wake up the so-called driving/fog lights.

FYI- The housing comes out of the cladding with a 1/8 th turn. Not sure if boilng would help you separate the lens from housing. Even if you could, the stock housing has a low wattage rating and using a 50 watt fog or driving light behind a factory lens will probably melt that "nissan" lens.
