Four Six




The World's Slimmest 4x6" Light 

Our ultimate goal was to do the unthinkable: Integrate the latest projector lighting technology into the slimmest headlamp design on the market. FourSix's bring peace of mind to those with little space to work with under the hood. But Not only are they the slimmest 4x6" projector light ever created, the FourSix's pack a punch. Designed with our own thermo-regulated LED optical module, you get a massive increase of light at less than half the draw of power. Step into the modern era with FourSix's while maintaining the classic timeless look your ride deserves.

Plug and Go.

Designed to be a replacement for stock sealed beams, these lights fit into most classic car headlight buckets without any modification. The wiring plugs right into your OEM socket and there's no need to modify your existing wiring. With the low amperage draw of LED's long gone is the world of ballasts and relay harnesses.

Unsurpassed Reliability

The task in designing the LED optical unit was to find the optimal balance of brightness, heat dispersion, and reliability. FourSix's come equipped with our ThermoCool LED that accumulated countless hours of testing and design. What you get is a rigorously tested LED optical unit designed to exceed 10,000 hours of run time. With light output over 2x stock headlights, you'll get a boatload of crisp white light while saving more than 80% amperage draw compared to OEM sealed beams.want even brighter lights? upgrade to our 30W system and boost your output!

Adaptive Power Control

Inline is an adaptive power control unit (PCU) that stabilizes voltage fluctuation. With only a 1.1 amp draw, you'll have less strain on your alternator and more power to bump your tunes. Even with power surges and dips, the PCU adapts to your voltage ensuring your lights stay on.



Built right here in the USA, pick between a shiny reflective chrome base or a beautiful gloss black base. Because our lights utilize real Projectors, all the light comes out of the center meaning color doesn't effect the output. want to get crazy? just give us a paint code and we will have our professional painters shoot a custom color for you.

HDR Switchback

The most advanced halo on the market, these solid LED rings feature switchback technology which can be used for day-time running lights and as turns signals in the same ring. Though their main purpose is not road illumination, they are often brighter than stock sealed beams!
