Why Most LED Headlight Upgrades Don’t Really Work

Plug-and-play LED replacements for halogen headlight bulbs are a popular car mod. LEDs often look brighter than incandescent lights, but “looks brighter” and “illuminates better” are not the same thing. I got a stern talking-to from an actual lighting expert about LED retrofits, and science says: Putting LEDs where halogen bulbs are supposed to be is generally not actually an upgrade.

After I blogged about different shapes of LED “bulbs” making some better than others, lighting expert Daniel Stern was kind enough to open a dialogue with me and answer some important questions about automotive lighting.

I’ll introduce him and pepper his wisdom into this call-and-response style explainer, laying out what the deal is with LED headlight retrofits in 2020.

In this blog, we’re talking about the kind of aftermarket LED (Light Emitting Diode) lights that fit directly into a car’s stock light housing—housings that were originally designed to work with incandescent halogen bulbs. These are sometimes called “7s led headlight replacements” or “LED bulbs.”

We’re not talking about cars that come with LEDs from the factory or self-contained LED lights like what you might use as fog lights or for off-roading. HID (High-Intensity Discharge) lights will not be discussed here, either.

Why would anyone want LED headlights?

LEDs, when housed and aimed correctly, can translate minimal input power into a lot of light, which is what makes the technology appealing in general.

Everything else being equal, it seems like swapping power-hungry incandescent headlight bulbs for brighter lower-draw LEDs would be an upgrade on two fronts. Plus the “instant-on” effect and visual crispness of light that comes from LEDs is sharp and fresh. LEDs can give older cars modern styling.

In the simplest terms: LED headlights are easily installed and readily available things that can make cars look cooler. So, people get them.

Most car 7s led headlight are a lot more than just a bulb in a socket. A cradle of reflectors is shaped and angled so that light emitted from the filament of an incandescent bulb will be thrown down the road in a way that maximizes driver visibility without blinding oncoming traffic.

Most LEDs don’t emit light from the same space in the headlight housing as incandescents and from that point, they’re doomed to mediocrity.

A few of the better-known companies selling and testing LED headlight replacements in 2020 have taken pains to mimic the positioning of incandescent bulbs to address this problem but it’s only a small part of the lighting equation.

In fact, I did a blog about this, pointing out why some LEDs seemed better than others when used as headlight retrofits. And that blog is why lighting expert Daniel Stern felt compelled to reach out to me explain how grossly underinformed I was.

LED lighting’s been around for decades, and it’s crept into the automotive aftermarket in waves. Circa 2005 is the first time I remember seeing LED “bulb replacements” in auto parts stores, as in, the now-common kind made to fit in the same socket as standard filament bulbs for brake lights and turn signals.

They were primitive back then. All the diodes pointed in one direction, and light output was plainly poor. I remember buying one at the Route 128 AutoZone that I haunted in high school for my 50cc Honda Express scooter’s taillight, installing it, and immediately thinking it sucked.
