  1. excellent Review by Scott

    Front headlight went out. I needed a good quality ballast from a reputable company. Order Tuesday received Friday. Now I can see at night again. Thanks!!!! (Posted on 2/1/13)

  2. perfect for tight places Review by Omar

    Awesome for even the tightest places in the car. I love how thin these are compared to the older HIDs i have used. (Posted on 9/23/12)

  3. Great Product Review by Brandon

    Easy to install and allows for different applications depending on your preference. It was great being able to replace my large, old ballasts for these nice, slim, sophisticated ones! I always come to Diode for my lighting and they haven't dissapointed yet. (Posted on 9/7/12)

  4. So simple to use! Review by Aaron

    It truly can't get any better. Just mount the ballast, plug in the corresponding wires, and Voila! I'm honestly amazed at how small these ballasts are, yet how sturdy and functional they are. Works wonderfully. (Posted on 7/24/12)

  5. Definite upgrade Review by Thomas

    I upgraded from the xentec ballast to these ballast on my 2005 Mustang GT with 5000k xentec bulbs. Even with the same bulbs the color and vividness improved. Before they had more blueish glare to them. Now it's almost Crystal White. Will buy these in the future. (Posted on 7/21/12)
