This Hella Marine 5.75-inch round lamp is a direct swap that runs a replaceable H4 high and low beam bulb, with improved optics that light the way without blinding oncoming traffic. It comes as a matched set of 2, so both sides get the upgrade at once. A simple, honest fix for classic vehicles and older boats alike.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Hella Marine 5.75-inch round headlight is a straight swap for tired old sealed beam units, and it's the upgrade a lot of older rigs have been waiting for. You get two lamps in the box, so you can do both sides at once and keep the pair perfectly matched. Each one runs a replaceable H4 bulb, which packs high and low beam into a single bulb, and the lamp is shaped to drop right into any standard 5.75-inch round sealed beam bucket. No cutting, no adapters, no drama.\u003c\/p\u003e\n\u003cp\u003eThe big difference from a factory sealed beam is right there in the design. An old sealed beam is one throwaway unit. When the filament finally dies, the whole lamp goes in the trash and you buy a new one. This Hella Marine lamp uses a serviceable H4 bulb instead, so years down the road when a bulb burns out, you just swap the bulb and keep the housing. That's cheaper over the life of the light, and it means a roadside or dockside bulb change takes minutes instead of a whole new lamp.\u003c\/p\u003e\n\u003cp\u003eHella Marine calls out improved optics without increased glare, and that matters more than it sounds. Plenty of cheap conversions just blast more light everywhere, including straight into the eyes of whoever's coming the other way. This one is engineered to put the light where you actually need it, down the road or across the water, with a clean, controlled pattern. So you see more, and the folks coming toward you aren't getting blinded. Better vision for you, less glare for everyone else. That's the whole point of good optics.\u003c\/p\u003e\n\u003cp\u003eThe 5.75-inch round format, sometimes called 5-3\/4 inch, is one of the most common headlight sizes ever made. You'll find it on classic trucks, older cars, motorcycles, tractors, and plenty of helm and utility light buckets. If your current sealed beams measure right around 5-3\/4 inches across and seat with the usual retaining ring, these are a direct fit. This is the standard lens version without an integrated turn signal, so it's the right pick when your setup already runs a separate turn or park lamp elsewhere.\u003c\/p\u003e\n\u003cp\u003eAn H4 bulb is worth understanding if you're new to it. It's a single bulb with two filaments, one for low beam and one for high, which is why one H4 covers both jobs. That keeps the wiring simple and the lamp compact. It also means replacement bulbs are easy to find just about anywhere, from an auto parts store to a marine chandlery, so you're never stuck hunting down an oddball part.\u003c\/p\u003e\n\u003cp\u003eInstallation is about as straightforward as it gets. Pop the retaining ring, pull the old sealed beam, plug the H4 connector into the back of the new lamp, and seat it in the bucket. One thing worth knowing up front: H4 halogen bulbs pull more current than some very old wiring was ever designed to carry. If you're working on a vintage rig with original wiring, it's smart to check the condition of your connectors and grounds first. On higher-output setups, running a relay harness so the load comes straight off the battery, instead of through a decades-old headlight switch, keeps the light bright and the wiring cool. It's a small job that pays off.\u003c\/p\u003e\n\u003cp\u003eHella Marine builds gear to a fit-and-forget standard, and these lamps carry that reputation. Quality glass, a solid housing, and a beam pattern that's been dialed in rather than just cranked up. For anyone restoring an older vehicle or refreshing the lighting on a boat, a matched pair of these is a simple, honest upgrade. And you'll notice the difference the very first night you head out.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e5.75-inch round format drops straight into standard sealed beam buckets for a no-cut swap\u003c\/li\u003e\n  \u003cli\u003eReplaceable H4 bulb combines high and low beam in one serviceable bulb, so you replace the bulb and not the whole lamp\u003c\/li\u003e\n  \u003cli\u003eImproved optics put light down the road without adding glare for oncoming traffic\u003c\/li\u003e\n  \u003cli\u003eSold as a matched set of 2 so both sides light up the same\u003c\/li\u003e\n  \u003cli\u003eStandard clear lens with no integrated turn signal, ideal for setups with a separate turn or park lamp\u003c\/li\u003e\n  \u003cli\u003eDirect replacement for old sealed beam headlights, no housing modification needed\u003c\/li\u003e\n  \u003cli\u003eHella Marine fit-and-forget build quality with quality glass and a solid housing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Hella Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat size is this Hella Marine headlight?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 5.75-inch round lamp, also written as 5-3\/4 inch.
