Compare the Glow
Each color has its own brightness. Tap a color to preview its glow on this page, then select it in the product options above.
How the colors compare: Green reads brightest to the human eye and is the one most owners start with, with Yellow close behind — the best picks for a true low-light locator. White, Orange and Ice Blue sit in the middle: still easy to spot, more balanced in tone. Pink, Red and Purple are the softest — pick these for character rather than reach. All eight share the same self-powered vial, and you can always swap the vial later.
