1 bulb came damage, the switch burn in. Minutes of usei am a field tech contractor basically a Mobile Heavy Equipment Mechanic and more times than not we have to work on equipment that has broken down in a dangerous spot. So I bought this system to put on my service van along with some other lights. I will say that right off two bulbs didn’t work. Customer service was very good to send replacements. The product over all looked so, so on first appearance, wiring looked like cheap junk from China. And the wire length was not very long especially installing it on a van, truck, etc. would probably be perfect for something like a Dodge Neon but other than that I recommend ordering extensions. Install isn’t hard pretty straight forward. I found that the bulbs and wire poorly connect to each other and also to the controller. They weren’t making good contact inside the connectors. So the lights would often stop working you would hit another bump.All in all I got about what I expected for the money. I just figure they might more consistently for a little longer. The ultimate disappointment came when I noticed none of the lights worked so upon further inspection I realized that simething in the controll unit shorted out and all but burned my van to the ground. All of the wire connectors were crisp black and melted on both the wire and controller. So my opinion is it’s unsafe junk and a waste of your money.Have to keep pushing wires in to head they won’t work half the timeGot the package in ony 5 days shippet across the earth! And Good qualityits a great product but now after 8 months they dont work maybe bthe company could replace the system for free since i have To take iT to have it uninstall and then re enstalledagianHi, I'm very happy with this product, but 1 of the light bulb isn't working properly, there is any way that you can send me a replacement, I think is defected. Thanks please let me knowLights are exactly what I was looking for nice and bright. Install is pain by nature not necessarily from any product flaw. I ended up making my own switch as the supplied one is bulky. Customer Service is awesome, received reply within 24 hours. Hope I used enough sealer to keep them in place & water out time will tell.Easy install, not as bright as expected but get the job done, Have had issues with the box getting wet and not working but after it dried out lights continued to work.Excelente calidad de iluminación, buena calidad de materiales
