Flasher caused numerous electrical issues with brake circuit and random dead batteries. Took a year and $400 to find the issue was the flasher. Truck was out for literally a year while we looked into it. Now the company will not even give my $ back. Horrible experience.

Thank you for your review! I am a little confused by your review, since you purchased the product from Amazon almost a year ago. You then contacted us today for the first time to say that you were having issues with the item, that again you purchased from Amazon almost a year ago. When we tried to assist you with the issue, you sent many emails using foul language. Even though the item was not purchased from our website and it was way past the thirty-day return window (again purchased almost a year ago), we then said that the item could be returned to us for a refund in the interest of customer service so how are we not giving you your money back?

So I reached out about the light having issues and changing pattern and color on there own which is a major issue for me as I do construction and need the lights daily and they could start flashing blue on there own. It turns out that the problem is with the membrane that lets it breathe. It allows water in and that is what causes the problem I’ve noticed it does it to multiple lights after heavy rain or washing. This is a big problem.

Thank you for your review. We are sorry to hear that you are having an issue with your light. I did not see any recent messages, calls, or emails from you about your order, so I will have one of our customer service team members contact you and get this issue taken care of for you.

If i could give zero stars, I would. The patterns will not save, and the switch is not easy-to-use. They are cheaper LCM flasher modules out there that are easier to use, and offer more patterns.

Thank you for your review. I am sorry to hear that you are not happy with your Z-Flash. I am not sure what you mean by "patterns will not save" since there is no software available to make custom patterns for the Z-Flash LCM Plugin Flasher For GM. The patterns are built in. I will have one of our customer service team members contact you for assistance.

The kit that was specifically for my 2500 Chevy would not work with in truck. Had to send it back after attempting to do update with service tech. Now I’m waiting for the old one to be received by you all before you send me a new one back. So far I’m not experiencing a good experience thus far. I don’t know how long it will take for the turn around now and the truck was suppose to be in the field already.

Thank you for your review! I took a look at your order, and I do not see that you tried to contact us about this issue. It sounds like the ground wire coming from the harness was not connected correctly. We have tried to contact you via phone and email to resolve this issue, but have not heard back.

This LCD zflash does not work on my 2024 chevy tahoe rst. Iv tried numerous times and spent hours trying to get it to work. Iv called customer service and no one responded. This seemed to be a great product to invest in, very disappointing

I ordered this rather expensive flaher set for my 2022 Ford F250. After fighting the wiring harness for some time and having to leave part of it poking out from behind the trim, I got it to work. It was pretty cool, but not as good as the marketing showed in the ads. It took a while to get around to installing it due to the number and location of the plugs. After a month or so, one of my front headlight surrounds, the "C" shaped light, quit working. It was intermittent and the just stopped. It would flash but not stay on for driving. I called and spoke to someone in customer service. They were going to talk to a tech and get back with me to sort out a solution. Several months later. Nothing. So i snatched it all out and tossed it in the attic. Several hundred bucks down the drain.
