NA Eunos pop up lights button

Hi all,
I’ve got a ’97/’98 NA Eunos Roadster. When the lights are on, the pop-up headlight button is the only switch in the cabin that doesn’t illuminate.

I’ve read that some of these switches have a bulb fitted, while others are just blanks and can’t be illuminated at all. Does anyone know which type mine is? It’s the later style switch with the black hazard button.

If it does turn out to be a blank, how straightforward is it to swap the button over from a switch that can take a bulb?

Thanks

I’m pretty sure that they are all illuminated by design. The bulbs in them are replaceable.
