If you have ever stood in the parts aisle debating between white fog lights for that clean, modern look and yellow fog lights that cut through rain, snow, dust, and fog, we have great news. Diode Dynamics has released their dual color fog lights, and the concept is simple but genuinely useful: one lamp, two colors, switchable on the fly. We spent time with these lights, walked through the color switching process, and looked hard at the details that matter most. In this guide we will break down how the Smart Select technology works, why the beam pattern stays consistent, how the plug and play installation goes, and how to decide between the SS3 and the Elite Series versions of these dual color fog lights.

Why Dual Color Fog Lights Make Sense

Most drivers already know which color they prefer. White output gives you maximum visibility and a crisp, contemporary appearance, while yellow output is the classic choice for cutting through poor weather like rain, snow, dust, and fog. Both are perfectly valid, and Diode Dynamics still sells dedicated white or yellow SS3 and Elite Series fogs for anyone who wants to commit to one. But if you have ever been torn between the two, these dual color fog lights let you stop choosing and simply keep both in your pocket. The value here is flexibility. On a clear night you can run white for the modern look, then switch to yellow when the weather turns. If you are still deciding what suits your build overall, our guide on choosing the right LED bulb color is a helpful primer on how color temperature affects visibility and style.

How Smart Select Technology Works

The color switching system is powered by what Diode Dynamics calls Smart Select technology, and once you have seen it in action it is very straightforward. To change your output color, you turn the fog lights on and off three times, leaving them on for at least 1 second but no more than 3 seconds each time. On the fourth power on, the lamp enters programming mode and automatically switches to the next available option.

Saving your choice is just as easy. Once the lamp is showing the color you want, leave the selected output color on for 5 seconds to save it. From then on, that is your color every single time you turn your fog lights on. No app, no extra module, no fussing with a controller.

Understanding the Reset Behavior

There is one behavior worth knowing so you do not get confused mid-cycle. The lamps reset to white after two complete cycles in programming mode. If the color is not changing away from white, that means you are still in reset mode. When that happens, leave the lights off for 5 seconds and begin cycling again to reenter programming mode. It is a small quirk, but once you understand it, the whole process feels predictable.

Another thoughtful detail: the Smart Select system is designed so that whether you flash your high beams or strobe the lamps, the output color stays the same. You are not going to accidentally trip the programming mode just by using your lights normally.

The Beam Pattern Stays Consistent

Here is the part we appreciated most, and it is something that often gets overlooked with dual color lighting. With Diode Dynamics dual color technology, the beam pattern remains consistent whether you are running white or yellow output. This is a real engineering distinction. On other brands, switching colors often leads to slight misalignment and an uneven cutoff, because the two color sources are not perfectly aligned within the optic.

Diode Dynamics ensured that regardless of the color you select, you maintain the exact same spread, shape, and sharp cutoff every time. In their words, you are changing the color of the light, not the performance of it. The performance you bought is the performance you get in either mode. For anyone who cares about a clean cutoff that does not glare oncoming traffic, that consistency is a big deal.

Installation Is Plug and Play

Installation is the same as the existing Diode Dynamics fogs, which is to say it is plug and play. You remove your factory fog assembly, drop the new lamp in place, and connect the included adapter into your factory socket. There is no cutting, no splicing, and no need to modify the harness.

Quick Install Steps

The process breaks down cleanly into a few steps, which we walked through during testing:

Step 1: Remove the Factory Fog Assembly

Pull your existing factory fog light out of its housing so the mounting location is clear.

Step 2: Drop the Diode Dynamics Lamp Into Place

Set the new SS3 or Elite Series fog into the same location where the factory unit lived.

Step 3: Connect the Included Adapter

Plug the included adapter into your factory socket, and you are wired in with no extra hardware. If you are shopping around and comparing options, it is worth browsing broader categories like LED Fog Light Assemblies and the XB LED Fog Lights to understand where these dual color units fit in the wider fog light landscape.

SS3 vs Elite Series: Which One Is Right for Your Build?

Diode Dynamics offers the dual color technology in two distinct product families, and they aim at different styles of build. Let us break down both.

The SS3: Off-Road Styled and Maximum Output

The SS3 is the off-road style option. It uses custom engineered tri optics and that distinctive amber backlight. By using TIR optics, Diode Dynamics can collect nearly all of the light from the LED and direct it exactly where you need it, which is how the SS3 earns the title of the highest output intensity of any 3 inch light on the market. In dual color form, the output lands between the sport and pro power levels. If you want performance with a more aggressive built look, the SS3 is the pick.

The SS3 also shares design DNA with the broader Diode Dynamics pod lineup, so if you like this optic style you can explore the matching SS3 LED Pods for additional lighting positions on the vehicle.

The Elite Series: Factory Inspired Sleeper Look

The Elite Series is for the user who wants a factory inspired appearance. It is an OE grade replacement built around a single piece optic that provides extreme width and high intensity, wider than any other aftermarket fog lamp out there, with a sharp cutoff so you are not glaring oncoming drivers. It also carries the integrated amber backlight. Diode Dynamics describes it as a true sleeper upgrade: it looks stock but performs nothing like it.

For the full details on that OE grade fitment and the single piece optic, check out the Elite Series Fog Lamps directly. Both the SS3 and the Elite Series are SAE compliant for legal on-road use when aimed accordingly, so you are covered whether you go aggressive or subtle.

Building a Complete Lighting Setup

Fog lights are often the beginning of a larger lighting build, and these dual color units play nicely with the rest of the Diode Dynamics ecosystem. They make a great addition alongside light bars and pods, all while being managed by the D switch panel for a clean, organized setup instead of a tangle of separate switches.

Beyond fogs and the switch panel, you can round out a build with LED bulbs, a hitch mount kit, or utility lighting, all engineered to work together seamlessly. That kind of ecosystem thinking is a big reason people gravitate toward a single lighting brand for an entire project.

Our Take

After going through the color switching routine, checking the beam pattern in both modes, and confirming how simple the plug and play install is, our takeaway is that these dual color fog lights solve a real problem. If you have been stuck between white and yellow, you no longer have to settle for just one. The Smart Select technology is intuitive once you learn the cycle, the reset behavior is predictable, and most importantly the beam performance does not degrade when you switch colors. Whether you go with the aggressive, high output SS3 or the sleeper, factory inspired Elite Series, you get the best of both worlds in a single lamp. Both are available now at Diode Dynamics, and if you are debating between the two, their dealer locator tool can point you to a shop nearby.

Frequently Asked Questions

How do you switch colors on Diode Dynamics dual color fog lights?

Turn the fog lights on and off three times, leaving them on between 1 and 3 seconds each time. On the fourth power on, the lamp enters programming mode and cycles to the next color option.

How do you save the color you want on these fog lights?
