Hella 500/500FF 6.4" Round Light Cover, White

Anybody who's mounted a set of Hella 500 or 500FF lamps knows the lens is the part that takes the abuse. Rocks off the road, salt spray on the water, dust on the trail, it all lands on the front glass. This cover is the fix. It's a 6.4-inch round white plastic shield that fits over the front of the lamp and takes those hits so your lens doesn't have to.

On the water, plenty of boaters run 500-series lamps up on the hardtop, the tower, or a radar arch for docking and running after dark. Off the water, the same lamps show up on bumpers, brush guards, light bars and overland racks. Either way, the lamp spends most of its life switched off, and that's exactly when a bare lens is most exposed to whatever the road or the water throws at it. Slip this shield on when the lights aren't in use and the lens stays clean, clear and scratch-free.

The shield is molded from tough plastic, so it shrugs off the stray stone and the grit that would otherwise pit or haze a lens over time. The Hella logo is molded straight into the face, so there's no sticker to peel and nothing to fade. The white finish keeps it low-key against a white hardtop, a light gelcoat, or a white truck, and it's easy to spot if you leave one on by mistake before you flip the lights on.

Marine life is hard on optics in a way that catches a lot of new owners off guard. Salt doesn't just sit on the surface. It dries, crystallizes, and works into every micro-scratch, and the sun bakes the whole lot in place. A lens that's covered when it isn't working simply sees a lot less of that. The same goes for a boat that spends time on a trailer behind a truck, where highway grit and stone chips do the same damage off-roaders deal with on the trail. Covering the lens for transit and storage is the single easiest way to add years to a good set of lamps.

This is the white version, and it's sold as a single cover. If you're protecting a pair of lamps, order two. It's sized for the 6.4-inch round 500 and 500FF housings, so double-check that your lamp is one of those before you buy. The 6.4-inch round is the common size across that series, but Hella builds the 500 family in more than one shape and size, so match the cover to the lamp you actually have on the boat.

Here's the thing about a stone shield. It's for protection, not for running your lights through. Fit it when the lamps are parked, trailered, stored, or covered for the off-season, and pull it off when you actually want the beam. That's the whole job. It's cheap insurance against a cracked, sandblasted or hazed lens that costs a lot more to replace than the cover does, and it keeps the optics doing their job for years.

Not sure which lamp you've got? Look for the 500 or 500FF marking on the housing and measure the lens opening. If it's the 6.4-inch round, this shield is your match. If you run a mix of shapes on the same rack, check each one, because a cover that's a hair off won't seat cleanly and won't stay put where it counts.

Care is about as simple as it gets. Rinse it with fresh water after a salty day, wipe it down, and it's ready to go back on. No wiring, no hardware to corrode, nothing to service. It's a small piece, but it's the kind of thing you're glad you bought the first time a rock pings off the front of your rig instead of your lens. Genuine Hella, molded logo, and a straight fit for the 500 and 500FF lamps you're already running.
