Hella Rallye 4000 Stone Shield 8.7in White 147945001

The Hella Rallye 4000 is built to throw light a long way, and a lens that big deserves protection when it's not doing its job. That's what this stone shield is for. It's an 8.7-inch round white plastic cover, molded with the Hella logo, that fits over the front of a single Rallye 4000 lamp to keep the lens safe from stone chips, road spray, salt, and grit.

If you run driving or fog lamps on a boat, a hardtop, a T-top bar, or a bull bar up front, you already know how much gets thrown at them. Rocks off the road. Sand and shell off a beach launch. Salt spray coming over the bow on a rough run home. The lens on a Rallye 4000 does real work, so covering it when the lamp's parked is cheap insurance against a chip or a haze that scatters your beam.

This is the white version, and it's opaque, so it's a park-it cover, not a driving lens. You pop it on when the lamps are off and stowed, then pull it back off when you need the light. The Hella logo on the face keeps the look clean and finished, which matters when the lamps sit somewhere everyone sees them, like a center console hardtop or the front of an overland rig.

Fitment is specific. This shield is sized for the Rallye 4000 series at 8.7 inches across, so it seats over that lamp and no other. It's sold as a single cover, so if you're running a pair of lamps up front, order two. There's no wiring and nothing electrical here. It's purely a protective cover, which means there's nothing to fail, corrode, or short out. Fit and forget, the way Hella Marine builds its gear.

Install is about as easy as it gets. Figure a quarter of an hour, and that's if you're taking your time. The cover fits over the front of the lamp and stays put. No tools, no drilling, no rewiring. When you want light, it comes right back off, and it stows flat in a console locker or a truck box when it's not on the lamp.

Who's it for? Anyone running Rallye 4000 lamps who wants them to still look and perform like new a few seasons in. Offshore anglers who deal with constant salt. Overlanders who beat down gravel and washboard. Anyone whose boat or truck lives outside, where weather works on an uncovered lens year-round. A cracked or hazed lens is expensive to replace and it hurts your beam pattern. A cover is a fraction of that, and it's reusable for the life of the lamp.

Care is nothing. Rinse it with fresh water when you rinse the boat or hose off the truck. If the white picks up grime, a little mild soap and a soft cloth brings it back. There's no coating to baby and no electronics to keep dry. Store it somewhere it won't get crushed and it'll outlast several sets of bulbs.

A couple of honest notes. This is the cover only, not a lamp and not a pair. It won't fit Hella's smaller lamps or other series, only the Rallye 4000 at 8.7 inches. And because it's white and opaque, don't expect to run your lamps with it on. It's there to protect the lens between uses, and it does that one job well.

It's backed by Hella's limited one-year warranty, and it ships the same day when you order before 3 PM ET on in-stock items. If you're not sure it matches your lamp, check your lamp's series and lens diameter first. The Rallye 4000 is the 8.7-inch round lamp, and that's exactly what this shield is cut for.
