SUPERIOR: Light output effectively illuminates the road for added safety at night. The Holley RetroBright 4x6 Rectangular LED sealed beams produce 18,000CD for low beam, and 37,000CD for high beam, which is nearly three times more light output than your original lights. Their beam pattern is well distributed for excellent width, long-range visibility, and added range in high beam mode. These patent pending lights were engineered entirely in the USA by Morimoto, the masters in performance automotive lighting.
QUAD HI-LOW: Because each 4x6 headlight has a high and low beam function, you can wire the new lights to work simultaneously with the optional adapters (SKU: H810) so that you have four low beams and four high beams, to maximum performance at night. (Click for Wiring Instructions)
FITMENT: The buckets behind old sealed beam headlights on most vehicles built between 1950-1980 are extremely shallow, making it nearly impossible to retrofit a modern LED-based headlight without sticking out or modification. Not the case with the RetroBrights, which were purposely designed with an ultra-shallow profile to ensure perfect fitment.
OPTIONS: They come standard with a warm-white LED that maintains the classic look. If you prefer the classic style of the housings, but prefer a more modern pure white light output, that is also an option. For those who want a yellow lens (and yellow light output) --you can also opt for the Euro lens conversion kit.
SERVICEABLE: Though the rated lifespan of each LED headlight is over 20,000 hours, the Holley RetroBright is designed to be serviceable. If a light ever goes out, the proprietary LED cartridge can be unbolted and replaced with a new one.
QUALITY: The heart of the headlight is powered with high quality LEDs from Philips-Lumileds. 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 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" Rectangle headlights, these are cross compatible with other sizes commonly known as H4651, H4652, H4656, H4666, HP6545, HP4651, HP4656, or HP4666. The RetroBright LED Headlights offer 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.
