Can you provide some mounting details and photos? Thanks
I used the three existing mounting holes that are on each side. (see red arrows)
The OE running lights use these same holes.
I used some 6mm bolts that I cut the heads off to hold the bottom bracket.
I screwed them in, and use some nuts to lock them down.
I drilled the holes in the bottom plate accordingly, and then used some more nuts to position the bottom bracket.
I made a bottom bracket to mounted it to these 6mm bolts.
After I got the bottom brackets where I wanted them, I took them off and drilled three 1/4" holes in a triangular pattern.
I did the same with the top plate.
This is so that I can adjust the lights.
I used 3.5"x1/4" pan head bolts, and locked them down with some nuts.
I used pan headed bolts because they were the only ones that were completely threaded in stainless steel.
I put some more lock nuts each bolt, and then put springs on the top two bolts.
The bottom bolt I just put another lock nut on top to hold it solid.
I didn't worry about making it look pretty, since no-one will ever see it, but me.
Here is a picture.

My purpose for these lights is to be noticed in the daytime. They are 16W LED, and they do put out a lot of light, but our headlights are so bright that I doubt they will be seen at night.
