You get both filaments in one bulb, 45 watts on high and 40 on low, at 12 volts with a P45t base and clean white light. It's a single bulb marked for off-road use, so order two for a matched pair.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Hella 7951 is an R2 halogen headlight bulb, and if you've got a vehicle or a piece of equipment that runs the old Bilux-style round headlamp, this is the bulb that lights it back up. R2 is the classic dual-filament standard. One bulb, two filaments, high beam and low beam in a single glass envelope. The 7951 runs 45 watts on high and 40 watts on low at 12 volts, with a P45t base and a clean white halogen output.\u003c\/p\u003e\n\u003cp\u003eHere's the thing about R2 bulbs. They predate the later single-base headlight types, and you'll find them in older European cars, vintage motorcycles, tractors, and a lot of restoration projects where the headlamp reflector was built specifically around the R2 bulb shape. If your reflector has that P45t socket and the bulb you pulled out had two filaments stacked in it, you're in R2 territory. Drop a modern single-filament bulb in there and it won't seat right, and the beam pattern won't line up with the reflector. The 7951 keeps the geometry correct so your low beam stays low and your high beam actually throws down the road.\u003c\/p\u003e\n\u003cp\u003eWe'll be straight with you on the legal side. This bulb is marked Off-Road Use Only. In the US the R2 type isn't a DOT-recognized headlamp bulb category anymore, so Hella and the distributor list it for off-road, show, restoration, and export use rather than daily on-highway driving. That doesn't make it a lesser bulb. It's the correct, properly made R2 halogen for the lamps that were designed for it. It just means you should check the rules for your region and your intended use before you rely on it on a public road. Plenty of folks run these in classic cars that only see car shows and weekend cruises, in off-road rigs, and in machinery that never touches a highway.\u003c\/p\u003e\n\u003cp\u003eThe light itself is standard white halogen. No blue tint, no color-shift coating, just honest warm-white light the way the original lamps were meant to glow. For a restoration that matters. A correct R2 bulb keeps the headlamp looking and performing the way the factory intended, which is exactly what you want when you've spent real time getting everything else on the car right.\u003c\/p\u003e\n\u003cp\u003eOne detail worth calling out. This is a single bulb. Most vehicles run a pair up front, so if you're doing both sides, order two. It's a common thing to forget, and nobody likes getting one bulb when they needed two. Buying the pair at once also gives you a matched set, so both headlamps age at the same rate and you don't end up with one side noticeably dimmer than the other down the line.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward if you've done a headlight bulb before. Kill the power, pull the old bulb from the back of the reflector, line up the P45t base, and seat the new one. One rule we'll always repeat. Don't touch the glass with your bare fingers. The oil from your skin creates a hot spot when the filament heats up and shortens the life of the bulb. Handle it by the metal base, and if you do smudge the glass, wipe it down with a little alcohol before you power it up. That one habit is the difference between a bulb that lasts and one that burns out early.\u003c\/p\u003e\n\u003cp\u003eHella's been making lighting for a very long time, and their bulbs have a reputation for consistency. Filaments that are wound and positioned accurately, glass that's clear, bases that fit without a fight. For an R2 application, where you're often working on something older that you care about, that kind of made-right consistency is worth a lot. You put it in, you aim it, and you don't think about it again for a long while.\u003c\/p\u003e\n\u003cp\u003eSo who's this for? Anyone keeping an older Bilux-equipped vehicle on the road or on the trail. Restorers matching the original lighting. Off-road builds running auxiliary R2 lamps. Equipment owners who just need the correct 12-volt 45\/40-watt bulb for a reflector that takes it. If that's you, the 7951 is the straightforward, correctly specced answer. Confirm your socket is P45t and your old bulb was R2, order two if you're doing both sides, and you're set.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eR2 halogen dual-filament design puts high and low beam in one bulb, keeping the original Bilux beam pattern intact\u003c\/li\u003e\n  \u003cli\u003e45-watt high beam and 40-watt low beam at 12 volts for correct output in reflectors built around the R2 standard\u003c\/li\u003e\n  \u003cli\u003eP45t base seats in the factory socket so the bulb aims the way the reflector was designed to\u003c\/li\u003e\n  \u003cli\u003eClean white halogen light with no blue tint, correct for restorations and an original-look headlamp\u003c\/li\u003e\n  \u003cli\u003eSingle bulb format lets you replace one side or order two for a matched pair\u003c\/li\u003e\n  \u003cli\u003eMarked Off-Road Use Only, suited to classic shows, restoration, off-road rigs, and export applications\u003c\/li\u003e\n  \u003cli\u003eHella build quality means accurately positioned filaments and a base that fits without forcing\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 is an R2 bulb?\u003c\/summary\u003e\n    \u003cp\u003eR2 is the classic dual-filament headlight standard, sometimes called Bilux.
