Wesbar, Anderson, Optronics. All seem to be about the same from my experience over the years. One of the things I'll caution against is if the light is 'self-grounding'. Meaning, it grounds by using it's casing against the trailer. It needs to have a pretty clean contact with the trailer. Galvanizing makes that hard. I had a set like this and I ended up taking each light apart, soldering a short lead to the ground on the backside of the light, then using SS Tek screws to attach the lead to the trailer. Before I did that, every once in a while a light would go out (losing ground) and I'd have to loosen it/play around with it/retighten (although I found out too tight was worse) to get it to work again. Since I added the leads, they've been perfect.
