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

I hate the RAM canbus system. I have a 2017 RAM 3500 DRW HO. I have two sets of 35w HID ballasts sitting in a tool drawer at home but couldn't use them because as soon as you start the truck, it shuts both headlights off and gives me a warning message on the dash.All of that being said, it was cheaper do buy a new set of 55w ballasts with integrated CANBUS decoders than it was to buy a set of HID decoders. These ballasts had great reviews, had CANBUS decoders, were 55W and arrived fairly quickly. I have been using them for about 1 week with approximately 4 hrs on them and they still start and operate fine. They make no sound when charging up and reach max brightness after about 8-10 seconds. The ballasts says max brightness at 3 seconds, but I find that they still grow in intensity up until about the 10 second range (really who cares about a few more seconds) I will update this post if they take a turn toward the negative.Update: I have been using em for about 2 months now. They operate fine and I dont have any error messages, flickering, or light fade. I have one ballast under the fender and one taped to the fuse block. The one on the fuse block gets HOT. It hasn't failed but I am a little concerned by how hot it gets.second Update: Been going on 4 months now and have had no issues. Have the truck switch set to "Auto On" and they don't have any problems cycling on or off. No canbus messages on dash and light the road very well at night.
