Introducing the Morimoto Sealed4 LED headlights, a game-changer in the 4x6" Sealed Beam LED market. These headlights offer both style and substance, with a unique design that sets them apart from the competition. In low beam mode, they utilize Nichia NCSW170C Series LEDs and Morimoto's Kuria Optic projector lens array to efficiently deliver 2400 lumens in a properly LHD-stepped beam pattern. When switched to high beam mode, they provide an impressive 4300 lumens of illumination. Quality is paramount with the Sealed4. They feature high-quality LEDs from Nichia-Japan, UV-coated polycarbonate lenses for durability, and heavy-duty die-cast housings that also act as heat sinks. A special PWM LED driver ensures consistent performance, even during extended use.

Just when you think: You've done your research and come across every last option in the 4x6" Sealed Beam LED market, these should catch your attention. While it's true there's only so many ways you can package a set of low and high beam LED-based optics into a small rectangular headlight; Morimoto's Sealed4 pulls it off in the most functional and attractive setup possible

Proprietary: The Morimoto Sealed4 is all-new, all-original from the ground up. Until now, there were basically three distinct products on the market. You have the high-end J.W. Speaker 8800 at the top of the totem poll. Then there are the cheap J.W. Speaker knock-offs, re-branded by companies A,B, and C...and last but not least you have the options like the Truck-Lite reflector-based 4x6" lights...again, re-branded by company X,Y, and Z. The Morimoto Sealed4 LED headlights are unlike anything else on the market.

Output: In low beam mode, Nichia NCSW170C Series LED's paired with Morimoto's advanced Kuria Optic projector lens array efficiently distributes 2400 lumens on the road in a properly LHD-stepped beam pattern. In high beam mode, the Sealed4 illuminates an extra set of optics, upping the overall output to 4300 mosquito-melting lumens there.

Quality: No expense was spared when designing the Sealed4. The heart of the headlight is powered with high quality LEDs from Nichia-Japan. These aren't cheap emitters to begin with. Your classic car has already withstood the test of time and the UV-coated polycarbonate lens will take a another couple decades worth of abuse without fading. You can feel the precision in the heavy-duty die-cast housings that double as a heat-sink. A special PWM LED driver resides inside of the headlight to keep the LED's running at their peak intensity, even during prolonged periods of use.

4x6" Standard: Designed to replace all 4x6" rectangular headlights, these are cross compatible with other sizes, found in the compatibility section below. The Sealed4 offers full low and high beam functionality. They come standard with H4 3-pin male inputs and should be plug and play on most classic cars / trucks.
