Philips has a new line of bulbs called Night Guide Platinum. They are made in China, unlike the Xtreme Vision that is mostly made in Germany.
The most significant thing about them is that they are available in 9005XS and 9006XS, the straight base variants of 9005 and 9006. No Silverstar Ultra or Nighthawks are available with the straight base, nor is Philips' own Xtreme Vision.
There are some cars that require the straight base bulbs and cannot use regular angle base 9005/9006, such as the 2nd gen LH cars like the Chrysler Concorde, and the late 4th gen 98-02 Firebird/Trans Am with the LMC sealed beam conversions. I want to install those LMC conversions, but they have been out of stock for a long time (even before the pandemic), and they're not accepting backorders. The cars requiring a straight base also cannot use HIR 9011/9012 since there is no 9012XS
The Nightguide Platinums are not listed on the Philips website, but they are sold at legit Philips vendors.
