SEMA 2025: Diode Dynamics Doubles Down On Power, Control, And Vehicle-Specific Fitment

Diode Dynamics showed up to the 2025 SEMA Show with a clear theme: give builders more control over lighting, along with cleaner, OEM-plus installs. From all-new chase bars and dual-color fogs to a refreshed Stage Series light bar lineup and an expandable switch system, here are the newest products you need to see.

The SS10 Chase Bar

Dedicated rear visibility is becoming standard kit for trail and overland trucks. The SS10 combines safety, legality, and quick control in a single bar — ideal for diesel tow rigs leading groups or prerunners kicking up roost.

The company’s SS10 Chase Bar is a purpose-built rear “chase” bar for increased visibility in dust, snow, and convoy situations. The SS10 packs 21 selectable chase/strobe patterns, three brake-light modes, and is CHMSL-compliant. A small magnet tool lets you change patterns on the fly — no digging into menus on a phone when conditions change.

New Additions To The Dual-Color Lineup

Amber punches through dust and fog; white is optimal for max output; red preserves night vision at camp. Swapping modes without swapping hardware simplifies wiring and saves space on already-packed builds.

Diode Dynamics introduced a Dual-Color family that lets one fixture do the job of two. At SEMA, they showed Elite Series and SS3 fog lamps with SmartSelect quick-color switching (white to amber) and dual-color rock lights (white/amber or white/red) that work with existing harnesses.

Infrared Lighting Coming To Stage Series

IR fills a specialty niche that’s growing with night-vision adoption in the off-road space. Also on display at SEMA: Stage Series IR options focused on “true infrared performance” with tight optical control and minimal visible red bleed—aimed at trail support, filming, or security/NVG use.

Stage Series Light Bars: Re-Engineered For Output and Control

This fall, Diode Dynamics formally launched its all-new Stage Series light bars, a ground-up redesign that dovetails perfectly with the SEMA message. Headline items include significantly higher intensity (flagship bars measuring into seven-figure candela territory), Standard vs. SmartSelect control options, section control on larger bars, interchangeable lenses (swap to yellow later), and CrossLink compatibility for modular linking.

Although the bar family’s big debut preceded SEMA by a few weeks, the revamped bars were a cornerstone of the booth narrative: more power, more flexibility, cleaner integrations.

D-Switch: Diode’s Expandable Eight-Channel Switch System

Lighting isn’t useful without control—and Diode’s answer is D-Switch, an eight-channel automotive panel built for 12-volt accessories with features like dimming, strobe, trigger wires, and app integration. For builders who want a single ecosystem, D-Switch pairs naturally with Stage Series hardware and the new Dual-Color pieces.

Replacement Headlamps And Tail Lamps

Diode Dynamics continues to expand its OEM-style replacement assemblies under the Elite Series banner (complete headlamp assemblies for select platforms like Jeep JL/JT and Ford F-150), with plug-and-play architecture, selectable DRL behavior, and show-mode features.

For broader vehicle coverage — especially Toyota trucks/SUVs — Form Lighting (a Diode Dynamics partner brand frequently featured alongside DD in community channels) offers full replacement headlamps/tail lamps with sequential turn signals and modern startup animations. For the fifth-gen 4Runner (2014–2024), Form’s projector headlamps are a popular OEM-plus swap and a good reference for what we expect as the sixth-gen develops.

2025 Toyota 4Runner: What’s Available Now

The 2025 and newer sixth-gen 4Runner is a huge target for lighting brands. Diode Dynamics already has multiple bolt-on Stage Series kits live, and the company says more 4Runner-specific mounts and kits are in development. This is such an important platform, it’s what Diode chose to display in its SEMA booth.

Available now from Diode Dynamics:

• Stage Series Backlit Ditch Light Kit (CAD-designed brackets; no cutting/drilling).
• Stage Series Reverse Light Kit (under-bumper dual-pod with plug-and-play tail-light harness).
• HitchMount LED Pod Reverse Kit and TRD Pro Grille Light Bar Kit, plus SS pods/CrossLink options.
• D-Switch hub mounting kit sized for the new 4Runner.

Final Take

SEMA 2025 made it obvious: Diode Dynamics isn’t just chasing raw lumen numbers. The brand is building a lighting ecosystem — bars with smarter control, fogs that change function on command, a chase bar that bakes in safety, and a switch system that ties it all together. Add in fast-moving vehicle-specific kits — like those already landing for the 2025 4Runner—and it’s a compelling, builder-friendly path to a clean, reliable lighting package with room to grow.
