So I try to leave more good reviews than bad reviews however today will not be good. These things are horrible quality it's almost like they were cheaply printed with the cheapest 3D printer you can get. The first said they shipped me, the 3157 ends were barely crimped together. They were also wired backwards so I had to take it apart swap the wiring solder them back together for them to still not work. Quick check with voltmeter reveals the little circuit board was Dead on arrival. So they were sent back in another pair were mailed out. This time the whole housing for the adjustment screws is broken and the headlight doesn't fit into the body line or trim at all it sticks out about an inch at the bottom. Also the adjustment screws did nothing I think they were literally just there for decoration. The day running lights on the second set still didn't work either. So what I think is they built one functional pair for their little gallery so you can see how great they look, then they produced all of these with zero quality control and started mailing them out. I know the shipper is just a small business but you should really stop selling these because it's going to hurt your reputation. I will not buy anything from DNA motoring again the quality is atrocious.
