Seems to be a very popular mod. I placed mine just left of the left ramp.
I too removed the stock light and installed a 555 led in the base hooked into the GI's.
Placement seems to be a personal preference.
On the last one mounted on the pop, I would think it blocks the upper lane view.
The first pic position I tried that but it got in the way with lifting of the pf for tweeking.
Looks good no matter where it is placed...good mod.
