What’s the difference between the D2S Kit and the D2H Kit?
D2S: Allows for OEM bulbs, or a D2S bulb from any other manufacturer to be used should you desire. Allowing for better output and longevity. Better bulb seating within the holder.
D2H: Cheaper, easier to install, theoretically should have the same output as D2S, however, if installed incorrectly, you may experience shadows in your output. Reinstallation should fix this. Should the bulb fail, you will be forced to buy another D2H bulb, and will have to wait for delivery/shipping as it’s not a “common” bulb that all supplies carry and is “aftermarket only”.
