ATTs Crystal Illuminated Wheel Bite Alarms

The Crystal ATTs alarms take the underlit concept further by combining the beneath-wheel LED with a clear crystal body that glows vividly in the chosen colour across its entire surface. The result is exceptional 360-degree visibility in the dark without any forward-facing LED that could affect night vision. All core ATTs features are fully retained.
