Here's something I thought I would share:

I got my light bar from them and the tabs are a great design. They come powder coated and the finish is very tough. I know everyone is going for the A-pillar mounts now, but I still like the fender mount.

 

Not bad looking, But very steeply priced. I would copy the design, and fab up some, (including a rubber gasket & grommet) before buying them!

 

Might just be the picture but I think the light will hang too far out. It looks like I would smash that light the first time my front tires decided to fling a rock.

 

I found them a while back and decided to make a set. I just cut some sheet metal (not sure of thickness). Bolted one piece to the fender and welded a tab for the light. Haven't had one break yet.

 

I dont really like the look of them, nor do i like the look of lights mounted to the pillers, i feel like they would get torn off easily when going through tight spots
