5x7 LED Headlights Holley X Morimoto for Classic Cars | HR Tested
There are numerous 5x7 headlight options for your classic car out on the market. Unfortunately, most have one or several huge downsides. It could be poor light performance, improper fitment, ugly styling, or bad build quality. Except for one. Holley and Morimoto have combined forces to introduce their new RetroBright LED Headlight.
Bringing to the market of sealed beam users, Holley has introduced a game-changer of an LED headlight. Built-in a compact, reliable, and period-correct way, these RetroBright Headlights are tailored to your classic vehicle. And with their range of sizes, you can be sure to find one that fits your vintage ride.
Built in a compact package, these brand-new LED headlights are meant for easy plug-and-play for your classic vehicle. Modern headlights with the same measurements as a classic vehicle, like these 7in Round, for example, are often much larger than their halogen counterparts from yesteryear. New LED headlights, or even halogen ones, have several bells and whistles built into them to do a variety of functions that inevitably increase the mass of the housing.
With Holley’s new addition to the market, they have taken the power and output of those fancy modern headlights and utilized it in a classic way.
It gets better from there. Not only do the RetroBright headlights look and fit like the OEM lights they are meant to replace, but they also come in two color options. First, is the 3000K color temperature classic white headlight. This is for those of you who want to fully commit to that period-correct look. Second, there is a 5700K modern-white color that also gives you a boost in light output over the 3000K lights.
These LED headlights will fit any vehicle with a power source of 9-18 Volts and they are 25 Watts. Lastly, we would also like to note that these headlights are SAE compliant.
While we are discussing the topic of output, Holley and Morimoto have created a monster of a headlight with respect to its packaging. When looking at the 3000K light, it produces 1280 max. Lux on low beam. This is 141 percent brighter than stock. The biggest improvement is the beam pattern. The stock light barely gives you any width in its beam pattern.
Once you flip the high beams on, the 3000K Holley RetroBright LED headlight puts out 1580 max. Lux. Even though it is only 43 percent brighter than the stock 1100 max. Lux, the coverage is incredible. You can see leagues more in both distance and width.
The 5700K RetroBright headlights perform even better than the 3000K version. You get 1460 max. Lux in the 5700K LED bulb, this is 175 percent brighter than stock. In high beams, this LED headlight emits 1890 max. Lux where the stock halogen headlight puts out 1100 max. Lux. That is a 71% difference.
You also need not worry about beam pattern differences between the two as they are identical with the exception of the obvious color temperature difference. These bulbs are also easily changed out. All you need to do is unscrew the two Allen screws on the rear of the housing. From there, you can remove the bulb.
Unlike several things on classic cars, these are super easy to install. Most often you will have a few exterior screws to remove a piece of bodywork holding in the headlight and its retainer ring.
Once the body panel is removed, unscrew the retainer ring holding the Holley LED headlight in place. Be sure to have a hand on the actual headlight since the retainer is the only thing holding it in place.
After you have the headlight out of the retainer ring, unplug the housing from the wiring.
You will notice here a big difference between the stock housing and the Holley RetroBright LED headlights. Where in the OEM housing, the plugs are built into the bulb, the RetroBright has a durable cable extending from the bulb. Fear not, the connectors are still the same and the next few steps are straightforward.
There are two ways you can install your light depending on your vehicle.
If your vehicle has only two headlights, one on either side of the vehicle, all you need to do is plug the light into the vehicle’s harness and then reinstall the retainer ring and bodywork if necessary.
If your vehicle has quad headlights, two on either side, then you may want to use the adapter. The adapter allows you to plug in both headlights into the adapter and have a total of four low beams and four high beams, as opposed to two low beams and two high beams.
Once you have chosen your route, you could run into the issue of the lights not working. Fear not! This likely means that your classic has reverse polarity wiring. To get your RetroBright headlights working, take the extra adapter harness and plug them into the housing or relay. From there, plug the three terminals into the factory connector that comes in the kit.
