HID LIGHTS can you install later

Then go buy a Prius with OEM HID lamps, You will be glad that you did. And don't leave them on in the daytime. Get a turn signal DRL conversion kit.

 

I can't think of any factory option that would be reasonable to retrofit in a Prius or any car. Except maybe leather, but you won't get the steering wheel.
Most options are deeply integrated and computer controlled more than may seem appearant on the surface. Always, always, always get what you really want when you buy a car. Don't settle for something less and rationalize you can retro-fit later. You'll just be disappointed in your purchsase.
If you can't afford it, save up until you can.

 

Note also that all Touring Editions have the HIDs.

For the $900 price difference between Standard pkg #2 and Touring pkg #2, the Touring pkg #2 is a real bargain -- you get the HIDs, fog lights, tuned suspension, bigger and nicer wheels & tires (plus a bigger spoiler, which I don't care for, but others do).

 

Wouldn't it be nice if some Manufacturer would sell their cars with all the wiring/connection points/bracket etc. already installed in the car so all anyone had to do was buy the option and plug it/fasten it/screw it in! In the long run it would be cheaper than financing the option over the next five years! I suppose it is because if you don't get the options at the beginning you will trade it in later for one with the options you wanted but maybe couldn't afford. That way they sell two cars.
