It's a bit tricky to define "appliances" that produce both heat and light, as many appliances are designed for one purpose. However, here are 10 items that can produce both heat and light, though not necessarily with equal intensity or in a way that is always intended:

1. Incandescent light bulbs: These produce light through heat, making them inefficient for both.

2. Halogen light bulbs: Similar to incandescents, they also generate significant heat.

3. Candle: The flame produces both light and heat, though the primary function is light.

4. Fireplace: A classic source of both light and heat, but more about ambiance than practical use.

5. Gas stovetop burner: Produces both heat and light, but the primary function is cooking.

6. Propane torch: Generates both heat and light, often used for welding and other tasks.

7. Welding arc: Produces intense heat and light during welding, with light being a byproduct.

8. Electric heater: Many electric heaters produce some light as a byproduct of the heating element.

9. Toaster oven: Heats food and can produce light as a byproduct, though it's not a primary function.

10. Space heater: Many space heaters will have a light indicator, even if it's just a red glow, indicating it's on.

Note: Some of these items are more about generating heat, with light being a byproduct, while others are designed for light with heat being a side effect.

It's important to remember that while some appliances produce both heat and light, it's not always their primary function.
