Bike rear light mud guard adapter post

Ever had situation when you have no space on saddle post to install rear light? Well, I had, so I made this simple adapter post which mounts on your rear mud guard. Drill two holes two cenimeters apart and use two 6-32 x 1/2" or similar metric screws with washers. Then mount your standard rear light onto post adapter.
I hope this will be useful to someone!
Thanks.
