When you see a red light on your flashlight, it is typically used for preserving night vision or signaling. You should adjust your eyes to the darkness and avoid shining the light directly into your or others' eyes.
A red light flashlight is used to preserve night vision and reduce glare in low-light conditions, making it easier to see in the dark without disrupting your eyes' ability to adjust to the darkness.

Need clarification please. The "it" you are referring to seeing, does that represent; A) the flashlight, B) the light from the flashlight, or C) "the speed of light"? Did you mean to imply that the flashlight was switched on? Is it an "old fashioned" bulb, an LED bulb, a laser light, or some other energy? Just wondering.
In a flashlight, electromagnetic waves are used to generate light. When electricity flows through the circuit, it excites the atoms in the light bulb's filament, causing them to emit light in the form of electromagnetic waves. The waves in the visible spectrum produce the light that we see when we turn on a flashlight.
