It's a high-output 100\/90 watt dual-filament bulb with a P43T base and a clear 3200K beam. Sold as a single bulb.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eHere's a straightforward replacement bulb that confuses people the second they read the box. 9003, H4, HB2. Three names, one bulb. They're the same dual-filament halogen with a P43T base, so if your equipment calls for any one of those, this Hella bulb drops right in. What makes this particular version different from the common one on the parts shelf is the electrical side. It's built for 24-volt systems and it's rated at 100\/90 watts, which is well above a standard headlight bulb.\u003c\/p\u003e\n\u003cp\u003eWhy three names? It's just history. Europe calls it H4, North America adopted 9003 and HB2 for the same specification, and the industry never fully settled on one label. The upshot is simple. Any of those three call-outs points to this bulb. You don't need to match the name, you need to match the base, the voltage, and the wattage.\u003c\/p\u003e\n\u003cp\u003eThat 24-volt rating matters more than anything else here, so let's start there. This isn't a bulb for your car or pickup. Passenger vehicles and light trucks run 12-volt systems. Twenty-four volts is the territory of heavy trucks, buses, and a lot of commercial, agricultural, and construction equipment. If your machine runs a 24-volt electrical system and uses an H4-style headlight, this is the right family. Put it on a 12-volt circuit and you'll get dim, orange, useless light. So check your system voltage before you order. It's printed on most batteries and in the operator's manual.\u003c\/p\u003e\n\u003cp\u003eThe dual-filament design is what the H4 pattern is all about. One bulb, two filaments, high beam and low beam in a single glass envelope. The P43T base has three tabs that index the bulb so the filaments land in the right spot behind the reflector. Drop it in, it only goes one way, and your high and low beams both work off the one bulb. The glass is a compact T4 envelope and the beam color is clear, a warm 3200K that's the classic halogen look. Nothing exotic. Just clean, familiar light.\u003c\/p\u003e\n\u003cp\u003eNow the wattage. At 100 watts on high and 90 on low, this runs hotter and pulls more current than a standard-output bulb. On a 24-volt system that works out to roughly 4.2 amps on high beam and 3.75 on low. More wattage means more light, and that's the appeal. But it also means more heat in the housing and more load on the wiring and switch. If your harness and headlight housing were built around a lower-wattage bulb, think it through before you jump up to 100\/90 watts. High-output bulbs like this are generally aimed at off-road, auxiliary, and work-light use, and high-wattage headlight bulbs aren't street legal everywhere. Check your local rules before you run them on a road vehicle. We'd rather you know that up front than find out at an inspection.\u003c\/p\u003e\n\u003cp\u003eInstallation is the same as any halogen bulb, with one rule that really matters. Don't touch the glass with bare fingers. The oil from your skin creates a hot spot that shortens the life of the bulb or cracks it. Handle it by the base. If you do touch the glass, wipe it down with rubbing alcohol and let it dry before you power it up. And a tip from years of doing this: replace bulbs in pairs. Filaments age, and a fresh bulb next to a tired one gives you two different brightnesses and color tones across the front of the machine. Swapping both at once keeps your light even and saves you a second trip in a month.\u003c\/p\u003e\n\u003cp\u003eThis one's sold as a single bulb, so order two if you're doing both sides. Hella has been making lighting for a long time, and their halogen bulbs are built to original-equipment standards, which is exactly what you want in a part that lives behind a lens and takes vibration every day. It's a simple part. But getting the voltage and the wattage right is the whole game, and that's where people trip up. Match your 24-volt system, respect the high-output rating, handle the glass carefully, and this bulb will do its job.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e9003\/H4\/HB2 designation: one bulb covers all three call-outs, P43T three-tab base for correct filament indexing\u003c\/li\u003e\n  \u003cli\u003eDual filament: high beam and low beam in a single glass envelope\u003c\/li\u003e\n  \u003cli\u003e100\/90 watt high-output rating for brighter light than a standard bulb\u003c\/li\u003e\n  \u003cli\u003e24-volt build matched to heavy-truck, bus, and commercial equipment systems\u003c\/li\u003e\n  \u003cli\u003eClear 3200K beam color for the classic warm-white halogen look\u003c\/li\u003e\n  \u003cli\u003eCompact T4 glass envelope\u003c\/li\u003e\n  \u003cli\u003eHella original-equipment quality, built for vibration and daily service\u003c\/li\u003e\n  \u003cli\u003eSold as a single bulb, order two for a full headlight pair\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\u003eAre 9003, H4, and HB2 the same bulb?\u003c\/summary\u003e\n    \u003cp\u003eYes. 9003, H4, and HB2 are three names for the same dual-filament halogen bulb with a P43T base.
