I bought these and used them instead of the little white plastic screws that hold the plate on - just replaced them with this and wired the running light to them instead - works flawless and looks pretty badass and clean. Nothing special, same deal for yours. If they're rated for 12v and you're just replacing the current lights - you'll be fine.
