HID conversion kits - quality differences?
there seem to be a dozen or so different HID conversion kits on the market. There are great differences in price, even for kits that carry the same specifications with respect to light color, output and life expectancy. For example, I have found 4000k-5000k light color kits for H7 replacement for as low as $300 on e-bay, whereas a number of online retailers charge up to $600 for the same thing from a different manufacturer. Of course everyone claims to sell nothing but the highest quality. Can you help decide what to buy? Are there real-world differences, or would one just pay for better service and a better looking website when buying from the more expensive places?
