We all love the look of classic sealed beam headlights, but the dim halogen light output makes nighttime driving a potentially risky endeavor for you and your beloved classic. Holley's new RetroBright LED Headlights offer a number of advantages over traditional sealed beam headlights such as plug and play compatibility, better visibility, and 6 times longer life. Not only that, but because they are LED they take up less space, create far less heat, and use less power than other headlights. Our low-profile housing design fits most shallow headlight buckets found on classic cars without the hassle of cutting or drilling. Holley worked closely with Morimoto, a leader in lighting design, to develop our line-up of lighting solutions that boast a classic look with modern lighting technology. A special PWM LED driver resides inside of the headlight to keep the LEDs running at their peak intensity, even during prolonged periods of use. For example, the 7" Round LED produces 32,000 Candela for low beam, and 53,000 Candela for high beam, which is nearly three times more light output than your original headlights. For a single replacement cartridge/bulb for a 5.75" Round Housing. Will not fit larger housings. Sold individually.
