Does anyone know where I would be able to purchase the bi-xenon projector headlights that come standard on the high end model, I've flipped all over the internet but can't seem to find any, I'd prefer not to purchase them from the dealership either, any responses will be greatly appreciated as always!

The 500x is not common enough to easily find in a breaker's yard. And it's not common enough to have people making copycat parts either. You may be very very lucky and find something on eBay but I doubt it.

I think your only realistic option is to go to a dealer and buy the parts. And you'll need more parts than headlight lenses bulbs. Xenon headlights are expensive and have more parts than halogen (ballasts etc). You're probably looking at over a grand for a full conversion.

And please don't get any xenon kits from eBay or the like. Shoving them in reflector lenses is both dangerous and illegal. It also looks stupid.

I found the standard headlights on my 500X very poor at night, dim and not carrying very far. I changed the bulbs for Philips Racing Vision. They have transformed the light output and beam pattern, the car is much better in the dark now. The bulbs can be bought for around £25.0 a pair on Ebay.
The only down side being they only have a life of 300 - 400 hours, but still much cheaper and easier than converting the car to HID type lamps. The bulbs came out top in the annual Auto Express magazine tests and are completely legal.

Yep, I used the similar Osram Nightbreakers for the high beams in my 500 hatch. Marked improvement.
