Found out tonight one of my headlight bulbs is out. I know it is only time for the other to burn out so I need recommendations on what I should buy to replace them.

I had a set of blue zenon (?) bulbs that another VX owner had purchased off ebay. Can't remember the brand name or the specs, but they lasted a long time and I liked the blue sheen they gave off.

I would like to go tomorrow and buy another set and have my mechanic put them on. Can I find something at Pep Boys or Autozone? Exactly what should I look for?

Thanks in advance. ;Dr;
