Product Details

2013-2018 Dodge Ram LED High Beam Bulbs: Looking for upgraded LED High Beam Bulbs from a reputable brand and value the fact that we've actually tested them on your truck? Our HR Tested kits include all the right components to ensure perfect fit, function, and performance from the upgrade. At Headlight Revolution, we do 2013-2018 Dodge Ram LED lighting upgrades better!

Aftermarket or OEM?: If you're looking to improve visibility on your Ram 1500/2500/3500 at night, you've probably found many options for LED upgrades. Most bulbs on the market are too big to install, don't work with the electrical system, and have no focus or hotspot in the beam pattern. Even if they come close on those aspects, they still aren't anything close to the quality you would find with factory-installed lighting. Like most aftermarket products, most LED bulbs are not engineered and tested for long-term reliability

With the SL1 LED: Diode Dynamics set out to engineer a true OEM-grade solution. With its compact size, optically correct output, flow-simulated cooling, and boost-mode electrical circuit, our SL1 LED patented design is a properly-engineered solution that finally provides a true upgrade in performance, with high reliability: and it's tested and validated to meet those standards, just like OEM lighting.

Compact Size: Your order includes two bulbs, to replace the factory low beam bulbs on your 1500/2500/3500. The bulbs are compact in size, in a patented design that isn't much bigger than the original halogen bulb. The drivers are compact too! If you have a sealed headlamp, they are designed to fit inside. The drivers and bulbs are tested to last over time, even when sealed inside with the heat of the headlamp.

Street Legal Output: Don't be fooled by high lumen numbers or "projector specific" bulbs. Your 1500/2500/3500 headlights are designed as a system, to focus light. If the light source in that system is out of focus, it doesn't matter how bright it is. You won't have a focused hotspot of light to shine down the road, you'll just have more glare. To correct this, the SL1 LED headlight bulb was engineered with advanced optical design software, which simulates each ray of light in a process known as "ray tracing." Using this tool, our engineers perfectly matched the filament location, allowing the SL1 LED to focus light just like your original bulb, preserving the focus and hotspot, with no added glare. It produces a functional low beam pattern on the road, with a clear hotspot and wide spread of light. This is a safe, functional output, in compliance with photometric standards, which we call Street Legal.

CANBUS Systems: Some vehicles use a CANBUS electrical system that can cause flickering or bulb-out warnings when LEDs are installed. These issues can be prevented with our Anti-Flicker Modules, which are designed to condition factory power signals, both by smoothing out flickering signals to the output, and by replicating the power consumption of a halogen bulb, to avoid vehicle "bulb out" warnings that usually come with LED power draws. Your vehicle uses a CANBUS system, so we include a pair of Anti-Flickers Modules with your order.

Tested to Perform: We test the SL1 bulb in factory headlamps, and measure the entire beam pattern using specialized equipment. It's an elaborate affair: a headlight is mounted to a computer-controlled rotating head called a goniometer. Light shines down a tunnel, where a sensor collects data as the headlight is rotated. The entire beam pattern is mapped, and we compare the total output to the original halogen, confirming that the SL1 bulb shines more light in the hotspot, without adding extra glare on the road. The test results speak for themselves: in most lamps, like the 2015 F-150 Halogen lamp, there is 30-70% more light in the critical hotspot, with no added glare or spread of light. With proper optical engineering, testing, and validation in the application, we can assure correct optical performance.

Staying Cool: You may have seen bulbs that use large straps for cooling, or big fans that just make noise. These bulbs still run hot, pushing the LEDs past their limits, resulting in degradation of output after a few months. When it comes to cooling, proper engineering is required to efficiently remove heat from the bulb. In the SL1, it comes together as a whole system that was extensively tested, with dozens of iterations to achieve the best cooling performance possible. It includes a direct-solder copper core board, thermal phase-change interface material, and thermally-modeled zinc casting get heat to the base, where base fins are designed for aerodynamic performance in conjunction with the flow rate and pressure of the Sunon bearingless microfan. The result is a highly-effective and reliable cooling system, keeping the bulb running at maximum potential.

Fitment: With its patented design, the SL1 LED fits where other bulbs won't, without cutting or modification. There's no hanging metal straps, just a compact bulb that plugs right in, with an exclusive reinforced shroud to keep the heat off any other components or wiring. Only slightly larger than a standard halogen bulb, it fits behind dust caps and in tight spaces. The driver and bulb are tested to function when sealed inside the headlamp - no worries about heat buildup! The base sizes on the bulb are also are keyed for exact applications, not one-size-fits-all, and the compact driver easily tucks away.

Driven: Rather than a simple buck regulator found on other bulbs, the SL1 uses a unique boost-mode circuit, which prevents thermal imbalance in the LEDs over time - again, just like you would find in OEM LEDs. It also has transient protection for long life in automotive circuits. Diode Dynamics engineers also analyzed dozens of OEM electrical systems, and added current-monitoring circuitry to mimic the electrical characteristic of halogen bulbs, drastically reducing the need for CAN-BUS adapters (though they're still needed on some applications).

Reliability: Every part of the SL1 LED was designed for reliability, from the custom wiring with strain reliefs and solderless terminals, to the exclusive zinc castings, to the reinforced high-temperature PP-GF plastics (the same used in halogen bulb bases). Each component was designed and tested, with dozens of variations of each component reviewed until we achieved the maximum performance possible. Finally, the SL1 was put through its paces in our environmental testing chambers - where the bulb successfully performed through dozens of thermal cycles, from -40 through 85 degrees Celsius (-40 to 185F). Whether you're in the Sahara or northern Canada, the SL1 will keep performing for years, and is backed by a three year warranty.

Made in the USA: If you're a lighting enthusiast who only buys American; Diode Dynamics is a clear winner in that category. One of very few brands in the automotive lighting industry who designs, engineers, and proudly produces their products right here in St. Louis, MO. We've sold their products for many years and are confident you won't be let down in the performance or quality departments. There's no better place to buy Diode Dynamics lighting upgrades for your car or truck.

2015 Ram 2500

Stephen Weston

Just installed the Diode Dynamics SL 1 kit. They are everything I'd hoped they would be. It was a fairly straight forward process that took about two hours to complete, including alignment.
The difference is very noticeable.
After a couple of hiccups in the shipping, everything needed to complete the job eventually arrived.
The support team was very prompt in sorting out the initial problem with the shipment missing one component and once it was all here everything went perfectly.

For $190 one would think this product is flawless and would have no problems but quite the contrary. Lights were dim from the get, and had one light already burn out on me. Also they sent me a faulty cannbus system from the get as well. Wouldn't recommend this product to anyone.

bulbs flicker

David Kartes

One bulb flickers. would not send another module without picture of damaged one. So go without a module until they send one. If they sent the module first you would not have to do the job twice.

Dad love the light.


Bought the lights for Fathers day and the old man loves them. I already have them on my truck as well. Dodge dies make their headlight a pain to install. Just make sure you pay attention to the + and - orientation. Groove lines up to fit both ways. Luckily is has built in electronics to prevent damage to the lamps.
