RetroBright 4x6-Inch Rectangle Headlight Lens Housing; Clear (81-86 C/K10)

Overview
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.
RetroBright has offerings to fit most classic and modern vehicles that utilize the popular 5.75" round, 7" round, 4"x6" rectangular, and 5"x7" rectangular headlight housings. They're available in 3000 Kelvin and 5700 Kelvin color temperatures depending on whether you're looking for that classic lighting hue or want an even brighter, more modern look. And if your vehicle feels more at home across the pond, we also offer headlights with yellow lenses for that European flair.
*Bulb Not Included (5700K Recommended). Sold individually.

When installing a RetroBright LED Bulb/Cartridge, tighten to approximately 18-20 inch-pounds, apply a small dab of medium (typically blue) thread locker, and be sure to use the thermal paste included in the box to maximize heat transfer from the bulb/cartridge to the housing (thermal paste is located in a small silver packet taped to the cardboard insert). For vehicles with extremely shallow headlight buckets, compare your available space to the drawings found above to determine sufficient space. Not all years and vehicles will have the exact same dimensions due to year or manufacturing differences as well as potential modifications from previous owners. Once fitted with a bulb cartridge, this model may not be direct plug-and-play with your application. An H820 Harness and unterminated male connector are included as a result. Sealed Beam Trade Numbers 4666, 4668, and 6545 with a non-standard H4 connector will require basic wiring modifications; de-pin factory female connector and replace with included standard H4 female connector. See instructions for details.
