Review on 2-Pack HYB Slim Digital HID Ballast 55W 12V - Universal Fit For H11, H7, H8, H9, H4 & More! by Non Martin

I purchased a xenonpro kit less than 6 months ago and the ignitors in the balast where already going bad. I purchased this kit to replace those. I replaced my passenger side 1st make it look fantastic, wires neat mounted all the components securely. I tested it and super bright. I continue and did the same to the driver side. Test it and driver side lights up but passenger side is out. Check my connections they were good. Test for 12v coming from the car it was good. I moved the Hid bulb to the driver side and it lit up fine. Ballast lasted all of 30 seconds. I love hid for the brightness but aftermarket kits are not worth the trouble. They are unreliable and you have to find somewhere to put all the extra wire and components. Modern LED headlights from a known good manufacturer are the way to go when replacing factory halogen bulbs.
