2 x 5500k D5S HID Xenon OEM Replacement Headlight Bulbs Limastar
PLEASE CHECK YOUR CAR IS. WITH FACTORY XENON HEADLIGHTS, NOT HALOGEN! This is for a PAIR of replacement D5S Xenon Bulbs.
Despite this they are still very high quality bulbs, see below for a more in depth explanation. These bulb ware over time, so if your headlights are not what they used to be or your car is more than 3 year old, it may be worth changing your bulbs, even if they have not blown. If a headlight has gone a orangey/pinky colour, it is just about to fail.
This is what xenon bulbs often do just before they fail. Single beam or Bi-Xenon use. High salt content metal base bulbs.
PLEASE NOTE YOU CAR HAS TO BE EQUIPED WITH FACTORY XENONS AND USE A D5S FOR THESE TO FIT, THESE WILL. These bulbs are the best quality on the market today. A lot of time went into researching which bulbs we were going to sell.
It therefor goes without saying that the bulbs we use are metal base bulbs rather than cheap plastic ones. A lot of people think the comparison of bulbs stops there, when in fact this is far from the truth.
There is a lot more to consider other than just metal or plastic base. There is salt content, electrode material, type of salt, and the list goes on. Yes your Xenon bulb has salt in it. The salt is the heart of your bulb and is used as fuel essentially. The air gap between the cathode and anode, and the firing voltage to excite the salts. Well this is what makes the bulbs tick. The less salt in the chamber, the less salt vapour and the plasma is more unpredictable generally producing more heat and less light output.This makes these bulbs run hotter and unevenly. The electrodes of genuine high quality bulbs are made from thoriated tungsten. A long time ago when microwaves were new technology, thoriated tungsten electrodes were introduced as an alternative to the use of pure tungsten electrodes.
1-2% of the electrodes are made up of thorium dioxide (ThO2) which makes the bulb last longer because the electrode is more robust. Cheap bulbs generally are made of pure tungsten which is super cheap. It erodes quickly, and the bulb life is short. It also stresses what little salts are in there and the output can be "wavy" or inconsistent over temperature and/or time. In general the luminous output is also less with a tungsten filament because more of the current flowing through the filament is transferred to heat versus being used to arc the salts (making more light).
These bulbs have been thoroughly tested against heat. Usually come winter time many people find themselves without lights, which is probably the time of year when you most need them.
These bulbs will perform no matter what the conditions outside are! We stock a range of temperatures to choose from. If the bulbs in your car came with the car from new they will be 4300k this is what most cars with Xenons come from factory with. You can change the temperature (colour) by changing the bulbs. Please bare in mind that the higher the temperature you go, the less light you will get, a lot of people think this is the other way around. Below is a chart to be used as a comparison of colour.
