Just installed the HIR bulbs, brand Toshiba made in Japan, and WOW what a bright light!! The stock bulbs were awesome but these $30 bulbs are incredible. Bought them from Daniel Stern Lighting, on the internet, and called him. IMO definitely worth it as my wife and I do much traveling in the LX during the dark hours. Next will be the IPF J01's and a Slee wiring harness.
