Overall sentiment: negative
Customer reviews:
I"ve purchased 2 sets of these and both times the ground connection went bad within a couple months.  I finally ended up hard wiring the ground in order to get them to work.  The connector plug is very low quality. 
 I would advise to find a different brand. My first set lasted less than seven months. Had to order a second set to make sure it was the anti-flicker harness that was making my light 3/4 less bright than the other (and it absolutely was the problem). I contacted customer service to voice my displeasure and their response to me was to make sure the harness was plugged in all the way. What do they think, am I an idiot? I will update/change my review if they ever rectify the problem by standing behind their product and crediting me for buying a second set of harnesses.... 
 did not work as described, don't know why I had to buy for the led light I purchased 
 Burned out within a week of driving and had to have it removed and bypassed. 
 Didn't work in my 2012 Jeep Wrangler with led headlamps, I bought someone else's and it worked fine! 
 Didn't need!! 
 Did not work my lights still flicker and now the product is in my tool box. I used it one time. :( 
 hi
One of the two is not working 
 I have had these on my jeep for less then 2 months and one burnt up. I mean litteraly burnt could have started a fire had I not been right there to smell something burning. I tried to contact the seller but was unable to I would not recommend this product. 
 Faulty 
 They do the job.... they are not weather tight. They don't clip in to my factory harness. I mean they fit but the locking tab does not engage. 
 They worked fine for the first 2 months, but one of them have already shorted out and stopped working, my light went completely out. I unplugged it, put the normal connector back on, and my light snapped right back on. 
 Tried these because I had a slight flicker but after installing cause the LED lights to randomly to shut off while driving. 
 Does not work at all had it professionally installed on my Jeep, does not work at all lights flicker still.
