I took a pair of unused trailer license plates (in Vermont, they're about 4"x6", aluminum and light weight) and a set of long plastic zip ties. By slipping the aluminum license plate (with a band of electrical tape, to keep from vibrating/rusting) between the lamp and the roll bar, I've created a shield that protects my eyesight, while still proving full forward illumination. The square roll bar makes easy to leverage the plate against a flat surface and allows the zip tie to tighten it in place. Simple and works great.
