Bests & Worsts Reviews from Amazon

So this is going to be a little bit of a Long review, but here it goes. Sometimes people will be unfair to the seller when a product doesnt work up to what they expect it to be. The item itself is well made, packaging is amazing, and the plug and play aspect was really easy to install. The LED is a bright white in color and there is a noticeable difference in the amount of light that these are putting out verses the old stock lights. So here is the draw back on the item. When I installed the item everything worked, but as I was driving my car a dash light came on, saying check engine. So I did a bit of research and found out that it is common when using LED because the car thinks that your headlights are burned out because the fact they are using less energy. Well I contacted the seller and this is why I gave them 5 stars. They understood exactly what I was talking about when I told them the problem and to correct the issue they sent me a decoder. The decoder basically tells the car that your headlights are good, bc it converts the proper wattage. The Decoder is $20 by itself and they sent it to me for FREE! I liked the lights so much that I ordered an additional set and the seller also sent me the decoder for those as well at no charge.
