Lucky you if you have a car that takes 9006 low beam and 9005 high beam bulbs, as the HIR 9011 and 9012 are terrific upgrades that provide aprox. a 85% increase in lumens on the low beam bulb, and about a 50% increase on the high beam bulb !!!! In my 96Q, I have been using the HIR in place of the high beam 9005, and it has been almost 3 years since installation and all still working great! Our highlander has had the low beam 9006 bulbs swapped with the HIR and also still working great after 3 years on the original bulbs!
Toshiba did stop producing these, and sold the patents to Philips- the bulbs are no longer bubble shaped, but more conventional looking, but are said to produce the same huge gains in output over the stock 9005 & 9006 bulbs. Some places may still have old stock toshiba bulbs, but not sure it is worth tracking down over the newer philips models. two highly recommended places I do business with that stock these bulbs are Candlepower Inc.in Rockville, Md- ask to speak with Kenny, who is very knowledgeable {google for their website} or
