The Kingswood had the light switches as standard.
The Sandman had them standard as well.
Base models will have the holes there, but no switch or wiring. However you could order (as an option) courtesy lights on a base model.

Remember to check the Body plate for Kingswood 8WN70 or Base model 8WM70

If you're looking at an HQ or early HJ, remember that the Sandman of these two series were based on Kingswoods as well, so you'd need more evidence.

Light switches/holes will be both sides.


Good luck.
