When ordering the Emisar D4V2, D4SV2, and many other Emisar/Noctigon flashlights, you have the option to choose which switch button light tint you’d like on your light.
Currently, the options are:
- Cool white
- Warm white
Backlit buttons: blue, aqua, cool white, green, warm white, amber, red
Backlit buttons in the dark: blue, aqua, cool white, green, warm white, amber, red
For me, these backlit colored buttons make the light easy to find in the dark and add a lot of character to lights like the D4V2 and D4SV2.
