    We all knew this, regulations change the market and I had always wondered why they didn't do this sooner...For the past decade (until recently) I never owned a vehicle without HIDs and it was rough at night driving rental cars...

    But man, I can recall the early-mid 2000s when everyone was replacing non-projector halogen bulbs with HID kits and blinding everyone...

    Dear GM, thanks for offering ACC on the Volt, now let's give it 7.2kW charging & a garage door opener...

    ExACTLY !!! But we must keep in mind that those were the people that were ignorant as to what was the PROPER car to put these kits into. And by those cars I'm talking about vehicles that were equipped with a true "projector" lens (looks like an eyeball). But I'll informed people, or they just didn't care....would put them in a car that had standard reflectors.

    And like you said, it would throw a blinding light in all directions. What made it worse was they were the ones that would buy the 55w kits. Glad that fad starting to die out for sure :rollseyes

    Many older cars with simple halogen (non-projector) headlamps have the correct housing reflector design, and upgrading them will not blind other drivers. My previous car here (see my past posts) was a 1995 Buick Regal sedan, whcih I drove for 21 years. I swapped the halogen bulbs (SilverStar) for new high-intensty-discharge bulbs (including the special transformer) in 2011, and the illumination improved greatly, yet the HIDs consumed less power than the halogens. The new owner is enchanted by the brighter lights as he is 90 years old and needs the brighter lights when driving at night. I also took the trouble of repolishing the housing lenses so there will be less scattering. When I swapped the bulbs, the LEDs equivalents were too expensive and not well made. Later I read that I was correct in not buying the first LED units sold.

    Now I have replaced the 9007 halogen bulbs in my present 2009 Chevy Equinox with 6000K Phillips LEDs and they work perfectly. My wife loves how they work and how visible the Equinox is at night. They also consume less power. I have replaced all interior and exterior lamps for LEDs (100%) and also polished the housing lenses, so now my 2009 Equinox looks and shines like a 2017 Equinox or better! I stongly recommend doing such swaps for all cars.
