These are new JLTV trucks, intended to replace hummer, do anyone knows what kind of mirrors are these? looks like "west-side"?

 

I think you mean West Coast Mirrors. (try google, lots of pictures).

Generically, what I see as West Coast Mirrors are a mounting bracket that is attached as shown in your picture, with the top/bottom of the actual mirror bolted to the top/bottom portion of the bracket. It allows you to pivot the mirror "in or out" but not up/down. It also is very unforgiving if you get to close to something - so keep that in mind. I drove ambulances in the NJ/NY area and loved this style of mirror.

 

Correct, west coast

I wonder who manufactures them for military - trucks? Truck-lite maybe?

Mind to elaborate more on why do you love these? any advantages?

 

I've seen them on newer F-650, F-750's. It has been years since I have seen them on anything lighter duty than that.

 

Cool retro look, but you'll be stretching your neck to see around the giant blind-spots they make..
