Holley RetroBright LED Headlights
Everyone loves 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 6x longer life. Not only that, but because they are LED, the lights take up less space, create far less heat, and use less power than other headlights. The 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 its lineup 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 in. 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 in. round, 7 in. round, 4 in. x 6 in. rectangular, and 5 in. x 7 in. 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, Holley also offer headlights with yellow lenses for that European flair. Additional details: * Plug-and-Play: Plugs into factory headlight harness for easy installation * Classic Styling: Retro styled headlight for period correct appearance * Superior: Over 2x the light output of halogens to keep you and your classic safe * Low Draw/Extended Life: Less current draw and 6x the life of halogen sealed beams * Compliant: No-glare beam pattern meets or exceeds SAE and DOT requirements * Serviceable: Replaceable LED cartridges for easy serviceability * Proper Fitment: Engineered to fit most shallow light buckets found on classic vehicles * Stronger: UV-treated polycarbonate lens won't shatter and is 10x stronger than glass or standard plastic * Compatible: Sealed Beam Trade Numbers: H5054, H6052, H6054 * Color Choice: Available in "Classic White" (3000K bulb) for a warm classic hue, "Modern White" (5700K bulb) for a cleaner modern look, or a Yellow Lens (utilizes 5700K bulb inside)

Holley Easy Level Fuel Level Senders
Holley Easy Level fuel level senders use LiDAR technology to precisely measure the depth of fuel remaining in your tank and work with all Classic Instruments' fuel gauges, including short-sweep, full-sweep, and selectable ohm range fuel gauges. They also work with many other gauge brands. Compatible with tanks ranging from 4 to 39 in., setup is a breeze with the on-board buttons. Easily set empty and full tank positions, with reserve, right on your workbench before installing and then set the empty, half, and full positions on the gauge. The desired dampening rate is adjusted with dip switches right on the unit to reduce fuel slosh and gauge bounce by adjusting how fast or slow the gauge reacts to the fuel level change. Upgrade Classic Instruments' gauge sets and other brands to capture the benefits of Laser imaging, Detection, and Ranging (LiDAR) technology with Holley Easy Level senders. This exciting and innovative automotive application replaces vulnerable moving parts with a hi-tech laser. Besides the problems encountered with float setup, hitting baffles or tank wall, Easy Level eliminates having to set up the float-type sender, saving time and effort. Features: * Quickly reads fuel levels with zero contact * Easy installation with no moving parts; popular 5-bolt flange * Long life sensor and no failing floats * Easy to program the level of any tank and electronic gauge * Bolt Circle Diameter (BCD) is 2.122 in. * Output is a PWM signal for 12 V applications (10 to 20 V maximum) * Mounting hardware and rubber gasket * Maximum operating temperature of 185 degrees Note: Does not work with OE-style gauges that utilize an ohm only input
