Ask yourself this - How come dealerships, who charge a single HID light bulb $175 to $450, can be sold at $49 a set? Yes, it's unbelievable, but it's true. The sad fact is, people lie. And when they tell you that an HID light or a conversion kit is made in Germany, USA, or Japan for a very low price, they are lying to you. Those are actually from China, and those dealers bought it twice or thrice less than the price of $49. Of course, if the price is that cheap, you don't expect the parts to be really good. In most cases, they are so bad that they only last for a couple of months. A lot of those cheap HID bulbs won't even last longer than 300 hours. Some won't even last longer than a short commute to and from the office.
When these things happen, what is your defense? Information, of course. It's best to know what makes an HID light genuine. Do you know how most money counterfeit checkers train their eye to know which money is fake or not? They don't focus on the bogus ones. They instruct their eyes to each tiny speck and detail of an original bill. Use this concept, too, when you are determining the genuiness of your HID lights.
So, what do you look for in a credible HID light? Look for these signs:
First, try to check if there is a ballast and a starter. HID lights require these things to function properly. Real kits include two sets, one for each light.
Also, look if the bulb has traces of filament. Most of the real kits have two sets, one for each bulb. Remember, HID lights DON'T HAVE FILAMENTS! They only contain Xenon gas. If you look inside, you'll see that there is a huge power line on the external part of the bulb. This power line completes the circuit in all HID lights.
Also, look for the power rating. If you see 55W or 100W, then it's definitely not an HID light. Real ones only use bulbs use 35W, 32 or 50W.
Lastly, look for clear bulbs. If the lens has a color to it, or you see words, such as "Filter" or "Colored Lens," then be very careful. In most cases, these are just regular halogen lights that are "filtered" or "reproduced" to look like some white color with bluish tints. If there is color in the lens, then you can bet that the lens are taking away some of the light's lumens. This means that it is not as bright as it should be.
Now that you know what to look for in a true HID light, be smart. Use what you've learned, and inform other drivers about it so they will get their money's worth all the time.
