Replace DRIVE green arrow?

Is there a way, possibly with an addon, to replace the S&H green arrow? I don’t want to remove or disable it, just change its look to something like the TomTom arrow and maybe move it down a bit. I need to check in edit mode to see about the latter.

The main issue I have with it is that as I’m driving around doing S&H jobs, my camera angle view means that the green arrow is pretty much a green rectangle. I have to periodically adjust the camera to look down at the car to see where the arrow is actually pointing. Not a game breaking issue but I do find it annoying.

I’m having an issue with the green arrow having way too much glow, and it just looks like a blob

It needs to be semi-transparent
