![]() Non-AFS xenon projector versions won't have the AFS motor at the bottom of the projector.Īnd non-AFS xenon projector versions have a "black" lens holder ring instead of a silver one. This holds the lens in place on the projector. Look at the 1/4inch ring around each projector lens. The xenon projector AFS type headlights will have this black box (with a white plastic piece behind it) attached to the bottom of the projector.Īnd AFS xenon projector headlights have "silver metal" lens holder rings. Most people do not realize that there were two different xenon projector type headlights for the same car, with the only differences between the two being the lack of AFS and a lesser performing projector (not as bright and not as wide). (3) xenon, projector type, no AFS, but with auto-leveling (however the projector itself is different than that of type 2) (2) xenon, projector type, with AFS, with auto-leveling (1) halogen, reflector type, no AFS, no auto-leveling Unbeknownst to many, the '04-'09 RX330/350/400h actually came with THREE options for headlights: If you decide to go with Kensun, this is the kit you need for your 07 RX350. Vehicles that do not have factory installed HID lights use size H11 for headlights, 9005 for high beams, 9006 for fog lights. The 2007 Lexus RX350 uses size D2S for headlights, 9005 for high beams, 9006 for fog lights for vehicles with factory installed HID systems. I read the reviews in Amazon's website, reviewers are saying that they have a very good customer should you experience an issue with their products. ![]() Then I read a post in this forum from a member who replaced his HIDs with a Kensun brand an seems pretty happy. I also did not want to buy on Ebay due to a considerable amount of negative reviews of buyers who have purchased HID kits and were promised a hassle free warranty and when they had a problem with the product that warranty was not there. My RX330 came with HIDs, I needed to replace the ballasts but I didn't want to spend an arm and a leg buying directly from Lexus. Their products come with a 2 years warranty. ![]() Their customer service is very good and they stand behind their product. Halogen bulbs are referred to variously as "tungsten halogen,""quartz halogen" or simply "halogen." The term "J" bulb (some manufacturers use the letter "J" in their halogen bulb designations) probably comes from the German word "Jod" which in English is "iodine," one of the elements in the halogen family.Anyone know a good place to order the kit? Thanks!I have heard very good things about Kensun products. Halogen is the name given to a family of electronegative elements, including bromine, chlorine, fluorine and iodine. The higher temperature filament also produces the "white" light often associated with halogen bulbs. The combination of this regenerative cycle and higher filament temperature results in a bulb that has a longer life and slightly higher efficiency than standard incandescent bulbs. Some of the evaporated tungsten is re-deposited on the filament. The tungsten filament evaporates as usual but the higher temperatures are sufficient to cause the tungsten to mix with the vapor instead of depositing on the envelope. Inside the quartz envelope is a vapor, originally iodine, now usually bromine. Halogen light bulbs utilize a fused quartz envelope ("capsule") allowing for higher temperatures. The lower filament temperature gives incandescent bulbs their typical orange-yellow, warm appearing light. This process requires incandescent bulb filaments to be heated less than optimally to give the bulb a reasonable life. When the tungsten filament is heated it evaporates and deposits metal on the cooler glass envelope (this is why incandescent bulbs appear black at the end of life). A standard incandescent bulb has a heat sensitive glass envelope that contains an inert gas mixture, usually nitrogen-argon. ![]() Halogen bulbs are technically incandescent light bulbs - illumination is produced in both when a tungsten filament is heated sufficiently to emit light or "incandescence." The difference between the two is in the composition of the glass envelope and the gas inside the envelope.
