I had one of the Xenon lights go our in my car. I swapped out the bulbs between headlights to test them so I am guessing that is my problem.

The good bulb is a OSRAM XENARC 66040; The bad bulb is a Philips 85122.

Does it make a difference what bulb I replace it with?

I see online a lot of people selling a Sylvania 66240 and a Philips 85122+ Is there a difference between the 66240 and 66040 or 85122 + and the 81522

Thank you for your help
