So far so good, they light the hid bulbs quickly and they are bright and reliable. I am the type of person who isn’t going to buy the cheapest item but isn’t going to buy the most expensive either. So these were middle of the market to me and I’m very happy with them. Still not too expensive and by the feel of them they are made well. Hope I do t need to but would order again.

I was hoping to extend my visibility at night while driving. They did brighten up the area a little. The problem is it continues to blow bulbs one after another.

UPDATE - 11/13/2019, seller contacted me and wanted to work out a solution, giving them one additional star . the product really was easy plug and play and worked as intended and designed . the problem I think is the incompatibility with my specific car's circuitry . IT ONLY happens (see below), when my car's automatic dusk sensor kicks in to turn the car's headlights on while already driving . it does not happen when my car starts with the headlights on, the ballast works as intended . but…

I've had the matching headlight bulbs replaced under warranty once right after I purchased these due to defective clips wouldn't keep them connected to the ballast. Now after just over a couple months it appears the ballast are dying.Edit- seller replaced ballast and all is good at this time.

I bought these to replace the DDM tuning POS ballast that blew after 2.5 months. In comparison it is now brighter than before. Great quality product, quick shipping, no error message, powers up fast, I highly recommend!

I had one go out in les then 2 months I'd like to warrant but it's almost impossible to do Even tho it says they have a year warranty

The first legit, good quality durable well made ballast ive ever bought, very happy and very satisfied with it very bright easy to install and very reasonable price.

these work great on my 2015 dodge dart and i don’t get a headlight out warning on the dash. seem to be heavy duty ballasts and made well

So far so good it’s looking great the ballest are bright, they turned my 6000k lights to about 4500-5000k and much brighter then 35w ballest, one of them is flickering when I first turn it on the flicker has been getting a bit longer on each start up since I Installed them so we’ll see what happens, my last ballest didn’t flicker and were on my car for 2 years

Easy to install, took about 10 minutes to swap these in place of my old ones.Very stable up until a few days ago, I've had them for a little over a year now. One of them started randomly shutting off after random amounts of time. 10 minutes, an hour. Usually happens a couple times a day now. Turning the lights off and back on fixes, but annoying.Overall, you're definitely getting a good product for the cost. Kind of sad there's only a one year warranty though.

Great Ballast! Worked perfectly on my 2015 Jeep Cherokee. Been driving around for a few days now and have not had any dash warnings or problems as I did with a previous hid kit I had purchased before this one.

It works right out the box, I have been using it for a few weeks now and it has been perfect. No Dislikes! I recommend this product

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

Product as advertised. I initially had an issue with a bulb arriving cracked due to shipping issues. Customer service was quick to send me a replacement. I'm really happy with this product, easy to install, fast shipping, outstanding customer service. Will definitely recommend to others looking for hid kits.

I have not been able to install due to one of the ballast was damaged when they arrived. However yhe seller was exremely fast at responding to my request for replacement. I will update this review when fully installed and tested. Overall very happy thus far.

All i gotta say is that it was definitely worth the money! Built quality is excellent and it made my HIDs waaaaay brighter. Alot of companies market their ballasts as 55w when they're really not. These definately are! It makes my headlights have the power of the sun, no joke. Would definately recommend and would purchase again.

I installed the Hybkler 55w canbus ballasts a little over a week ago to run my new hid low beams. So far I love them, super bright & come right on without any error codes. I bought another pair to upgrade my high beams and just got done installing those about 10 minutes ago. So far I highly recommend! High quality for a really great price!

So far working well and we're easy to install. The can bus did not work to get rid of my error code so that is why I am not 5 stars happy with this product. Lights do work correctly but have indicator light on in dash saying light is out.

Worked fine for a solid couple months, no issues, had one fail to where the light works intermittently. Swapped the ballasts and the problem stayed with the bad ballast so I know it’s not the bulbs. Have to turn my lights on and off repeatedly to get the headlight on now so I can drive at night. They worked great until one broke but now I need new ballasts.EDIT: Bought another set, relocated to be further from headers and I've had less issues. These don't perform well in colder weather either…

Great item and phenominal customer service by the seller. The ballasts are very powerful and make it easier to see at night. Thank you again!
