Headlights, HID, Blue Lights
I too am confused by the new "HID simulated" headlights. I have the H1 low beams, 9006 (55 W) are my fog lights and the 9005 are my high beams (65 w).
I picked up some from E-Bay... here is what I found.
Back in 2005 people were buying bulbs, adding a blue tint, and reselling on E-bay. They are crap.
In 2010 the replacement HID bulbs. They they flickered after a year.
In 2015 they came out with LED bulbs, but required fans in them. They lasted two years, the fan would fail, then burn out the circuits to run the bulb.
