The Vexilar Mag Shield (part no. MS0001), is a very useful accessory to add to your Vexilar. The cover fits both the FL-8 SE and FL-18 flashers.
Not only does the shield protect the display from moisture and debris (such as ice and snow), the shield magnifies the display, intensifies the color variations, and increases the viewing performance in all light conditions.
No tools are required for installation. Easy press-on friction fit.
