Review on Waterproof LED Trailer Stop Lights with Brake/Parking Function and Waterproof Connector for Truck Trailer RV UTE UTV - WildAuto 7'' by John Lewis

[UPDATE] Vendor was very communicative with me to resolve the issue. Apparently there was a problem with the start of production. They solve the problem and deliver new lamps when they're done. Because of the problem, they change this stack to a brightness. The new series version will be available with two levels of brightness. The build quality is good, except for the lack of brightness. The plastic is thick, not thin. They are bright and clear with good reflective quality. I'm waiting for a new batch. I'll revise my review when I get the new headlights.[/UPDATE] The round headlights look great and feel well built. However they are sold in dual intensity for the turn signal/tail light function and only one intensity worked. I ordered ten lamps, none of them worked at double intensity. Only the red and white pair worked. Black/White No. I have tested several different 12V sources and confirmed that the sources work with other light sources. I tried to contact the seller but never got a reply. Taking back goods and handing them over to another supplier/manufacturer.
