Yes I have a 2007 DL650. As long as there is an inline fuse, it still seems alright under or over the bars. Or did you mean it could get wrapped around your neck in an accident?The year/model matters because of the options available to you and the challenges posed by each model. I made myself this when I needed to mount soem switches/etc on my Gen 1 V-Strom.
That was followed by a bunch more for other peple like this one (still Gen 1).
And later when the 2012 DL650 shelves that look like this.
2017+ DL650s and 2014+ DL1000s don't support the same kind of shelves around the ignition switch, but they can use one like this.
Since you are asking about adding a socket, instead of replacing the existing socket, you probably have a Gen 1 or 2 DL650 or Gen 1 DL1000.
Lot's of guys just drill holes in the plastic panels. the reason I came up with the shelf in the first place was I didn't want to drill holes in the body work, but most importantly I decided the routing of the power cords was safest going to the center of the handlebars instead of under or over them.
