Just wondering if, when Pontiac went to the 4703/4701 headlight bulbs, were there any other bulb choices other than standard halogen? I'm talking about GE's Super Blue or Sylvania's Cool Blue or Wagner Britelites. I know right now there are the Sylvania Xtravision, but that seems to be it. There are several non-conversion, non-HID upgrades for other sealed beams. So whats up with this oddball bulb series? Sorry, just thinking out loud I guess.
