Hella 500 Series 6.4-Inch Round Light Cover, Black

Auxiliary driving and fog lamps live a hard life up front. They're the first thing to catch a kicked-up stone, a low branch, or a face full of gravel on a rough approach. This is Hella's answer, a 6.4-inch round stone shield that slips over the lens of your 500 and 500FF series lamps and takes the abuse so the glass doesn't. It's black plastic, molded with the Hella logo, and it's sold as a single cover.

So when do you actually use one? Any time the lamps aren't lit. Trailering the rig down the interstate, running a rough two-track out to the launch, or parking where road spray and grit are going to work on that exposed lens. Pull the cover off when you need the light, snap it back on when you're done. It's the kind of cheap insurance that pays for itself the first time a rock that would've cracked a lens just bounces off a plastic cap instead.

The 6.4-inch round size is matched to Hella's 500 and 500FF series lamps, the common round driving and fog lights you'll find on trucks, off-road rigs, boat towers, and hardtops. If that's what you're running, this is the cover made for it. Measure your lens face before you order if you're not sure which series you've got, because a stone shield only does its job when it seats properly over the lens.

Fitting it couldn't be simpler. There's nothing to wire, nothing to bolt, and no bracket to modify. The cover pushes on over the front of the lamp and holds itself in place, and it comes off just as fast with a tug when you're ready for light. No tools, no fuss. If you've got the lamps mounted on a tower, a bull bar, or a light bar, you can cover and uncover them without ever touching the mount.

Hella builds this the way they build the lamps, with material chosen to shrug off UV, salt, and years of sun without going brittle or chalky. That matters for a part that lives outside full-time. A cover that cracks after one season isn't protecting anything. This one is meant to stay flexible and hold its shape, so it keeps sealing over the lens year after year.

On the water, the enemy is a little different. It's salt spray, UV, and the constant damp that dulls and hazes an exposed lens over a season on a tower or hardtop. Cap the lamps when you're not running them and the lens stays clear, so the beam is still crisp when you flip them on for a late run back to the ramp. Same idea as trailering, just a saltier version of it.

Blacked-out looks are a bonus. With the covers on, a row of exposed lenses turns into clean black discs, which tidies up the front of a rig or a boat's hardtop when the lights aren't earning their keep. The molded Hella logo tells you it's the genuine part, sized and shaped for the lamp instead of a generic cap that fits loose and blows off at speed.

A couple of honest notes. This is a single cover, not a pair, so if you run your lamps in twos you'll want two of them. And it's a protective cap, not a lens or a filter, so you can't drive or run with it on because it blocks the beam completely. It's purely there to guard the lens when the light is off. Simple job, done well.

That's really the whole story. It's a plastic cover for a light. But if you've ever replaced a cracked driving lamp lens after a gravel road did a number on it, you already know why a few dollars of black plastic up front is worth every penny. Keep one on each lamp you're not using, and then forget about it. That's the Hella way.
