I recently finished replacing my round running lights with some angel eye fog lights, and installed the factory Isuzu switch. The switch was a little loose, but with a little shimmin' it fits just fine. The text on the switch lights up, and there is an indicator light to let you know when the lights are on. I don't know if you could sand the text off as it does light up from behind so the text is cut out of the black plastic of the switch. I went to a u-pull-it yard with the switch in hand and yanked a wiring harness out of a Passport. The harness was missing a wire, but it was easy enough to rig one in and it fits the switch like a glove.
Let me know if you want some pictures, and I can dive into my dash this weekend.
