What tool features a built-in light for soldering?

A soldering gun is specifically designed for tasks that require quick heating and the capacity to deliver high amounts of heat in short bursts, making it particularly effective for soldering components. One of the notable features of many soldering guns is the built-in light. This light is beneficial as it illuminates the work area, allowing for precise soldering, especially in tight spaces or poorly lit environments. This feature can enhance visibility and improve accuracy when aligning components to be soldered.

In contrast, while a soldering iron is a common tool used for soldering, it typically does not come with a built-in light. A heat gun is primarily used for tasks like shrinking heat shrink tubing or soldering larger connections, and does not include a light feature. The desoldering pump is a tool for removing solder, rather than applying it, and therefore lacks any feature related to soldering light.
