Are Morimoto XB Evo headlights brighter than the original XB? The truth is that the new XB Evo headlights are significantly brighter than the old style on average 2x – 4x brighter with the new technology update. If you’re on the fence between getting your hands on the old Morimoto XB LED headlights, or the new Morimoto XB Evo LED headlights, and you want maximum brightness, the old versions don’t stand a chance!
The question is fairly straightforward, but the answer often gets lost in marketing noise. Claims of “revolutionary performance” and “game-changing brightness” are easy to make, and most consumers have no way to verify them. That’s what makes the Morimoto XB Evo headlight launch particularly interesting: there’s real, standardized testing data available across five different vehicles that lets us evaluate the brightness improvements objectively.
In this analysis, we’re going to walk through the multi-point testing results for the XB Evo lineup compared to both factory headlights and the original Morimoto XB generation, looking at what the data tells us about LED headlight technology in 2026 and whether the upgrade claims hold up to scrutiny.
Understanding the Testing Methodology
The multi-point testing methodology used here was developed by Headlight Revolution and provides standardized scoring across vehicles.
All of the brightness data referenced in this article comes from the Morimoto multi-point testing system, which evaluates headlights using eight measurement points: six for low beam and three for high beam (two of which overlap). At each point, light intensity is measured in candela, and the readings are processed through a weighted formula that produces three sub-scores: distance zone (how effectively the headlight illuminates the road ahead), high beam (intensity and reach in high beam mode), and width (how broadly the beam covers the driving lane and shoulders). These sub-scores combine into an overall rating on a 1–10 scale.
This methodology is consistent across all tests, and all measurements are taken from a single headlight (driver side) under controlled conditions. The visual comparison photos show both headlights installed on the vehicle, but the numerical data comes from single-headlight testing to ensure apples-to-apples comparisons. With that framework in mind, let’s examine what the data reveals.
Vehicle-by-Vehicle Brightness Breakdown
Toyota Tacoma (2016–2023)
The Tacoma testing produced the most dramatic improvement in the entire XB Evo dataset. The original Morimoto XB headlight scored 1.7 on low beam distance and 2.0 on width, with an overall rating of 3.8. While the beam pattern had decent control with minimal foreground spill, it was simply too narrow and lacked the distance reach expected from a premium aftermarket headlight.
The XB Evo Hybrid immediately changed the picture with a 7.0 low beam score, 6.5 high beam, and 5.4 width for an overall of 6.8. The full XB Evo added its dedicated D-optic high beam projector and scored 7.0 on low beam, 9.1 on high beam, 5.7 on width, and 8.0 overall. With the supercharged driver installed, those numbers climbed to 9.2 low beam, 11.7 high beam, 7.7 width, and 9.6 overall. The percentage improvement from original XB to XB Evo (DOT-compliant) is 111%, and with the supercharged driver, it’s a staggering 153%.
Dodge Ram (2009–2018)
The Ram platform offers a useful comparison because the original XB was already one of the strongest performers in the aftermarket category for this truck. The OE reflector headlights scored 2.7 overall, while the OE projector headlights actually performed worse at 2.2. The original XB dramatically improved things with a 7.8 low beam, 8.3 high beam, 3.1 width, and 5.5 overall.
The XB Evo lineup improved upon this with the Hybrid scoring 6.4/6.4/4.0 (low/high/width) for a 6.4 overall, and the full XB Evo scoring 6.7/7.1/4.1 for a 6.9 overall. With the supercharged driver, the XB Evo reached 6.9/9.4/4.8 for a 7.9 overall. An interesting observation here is that while the raw low beam distance score actually decreased slightly from the original XB’s 7.8 to the Evo’s 6.7, the width score improved by 32% (3.1 to 4.1), and the high beam went from 8.3 to 7.1 in stock form but to 9.4 with the supercharged driver. This suggests the Evo’s projectors are optimized for a more balanced beam profile rather than concentrating all output into a narrow distance hotspot.
Ford Super Duty (2017–2019)
The Super Duty data is especially revealing because it compares the XB Evo to both stock halogen and stock LED headlights. The stock halogen scored 3.3 overall (6.5 low beam, 3.2 high beam, 5.1 width). Surprisingly, the factory LED option scored even lower at 3.1 overall (1.3 low beam, 5.6 high beam, 2.2 width). The LED headlights suffered from excessive foreground illumination with a poorly refined hotspot, demonstrating that LED technology alone doesn’t guarantee good performance without proper optical engineering.
The XB Evo scored 6.5/6.9/4.8 for a 6.9 overall, more than doubling the factory headlights’ performance. With the supercharged driver, scores rose to 7.8/10.1/6.7 for an 8.8 overall. The Super Duty XB Evo uses four bi-LED projectors per headlight, each driven at approximately 25% potency (the compliance strategy distributes the load across more projectors rather than driving fewer projectors harder). This approach yields excellent beam uniformity and a natural convergence of all four beams at the 30-meter target distance.
Chevrolet Corvette C6 (2005–2013)
The Corvette C6 presents unique optical challenges due to its extremely angled headlight lens, which limits what any projector can achieve in terms of beam pattern optimization. The stock HID headlights scored just 2.0 overall, partly because the D3S HID bulbs lose brightness over time and the reflector bowls tend to degrade from heat exposure.
Morimoto’s XB Gen 1 (C7 style) improved things to 3.8 overall, but the XB Gen 2 (C8 style) actually regressed to 1.8 due to severe foreground flooding caused by the projector placement and lens angle. The XB Evo Hybrid brought the score to 5.0 with a notable 7.3 width score, and the full XB Evo reached 5.9 overall with an exceptional 10.5 width score thanks to its side-shooter LED technology. While these absolute numbers are lower than the truck scores, the relative improvement from stock (2.0 to 5.9, a 195% gain) is actually one of the largest in the entire dataset.
Ford F-150 and Raptor (2009–2014)
The F-150 testing produced the most impressive absolute numbers of any vehicle. Stock halogen headlights scored 2.1 overall, and the OE HID option managed 2.7. The XB Evo (both Hybrid and full Evo share the same bi-LED projectors) scored 6.9/6.7/4.8 for a 6.8 overall in DOT-compliant form.
With the supercharged driver, scores jumped to 9.4/9.3/6.7 for an 8.8 overall. However, the full XB Evo’s ace in the hole is its integrated one-banger pod lights as auxiliary high beam assists. With those engaged alongside the supercharged driver, the high beam score hit an extraordinary 14.3, pushing the overall rating to 9.3. This is the highest overall score ever recorded on the multi-point testing system for any headlight on any vehicle, making the F-150 XB Evo the current performance benchmark for the entire aftermarket headlight industry.
Cross-Vehicle Patterns in the Data
For the manufacturer’s perspective on the technology behind these numbers, see Morimoto’s full XB Evo headlight lineup.
Looking at the data across all five vehicles, several consistent patterns emerge that tell us something meaningful about the XB Evo’s engineering approach.
First, the width improvement is universal. Every vehicle showed a meaningful gain in beam width from the original XB (or stock headlights) to the XB Evo. This reflects the Evo’s use of improved projector optics and, in some cases, dedicated side-shooter LEDs. Wider beams improve safety by illuminating road shoulders, intersections, and potential hazards in your peripheral vision.
Second, the dedicated high beam projector (D-optic or one-banger) consistently adds 1–3 points to the high beam score. This feature, exclusive to the full XB Evo models, is arguably the single most impactful upgrade over the original XB in terms of raw performance numbers.
Third, the supercharged driver delivers remarkably consistent gains across all platforms, typically adding 1–2 points to the overall rating. This consistency makes sense given that it’s simply unlocking additional capacity from the same projectors rather than changing the optical design.
Fourth, and perhaps most importantly, the XB Evo achieves higher scores than the original XB at lower projector drive levels. The new projectors at 50% capacity outperform the original XB projectors at their full output. This means the Evo has substantially better optical efficiency, getting more usable light on the road per watt of LED power.
What This Means for the Aftermarket Headlight Market
For a deeper look at how the XB lineup compares to competitors, see The Retrofit Source’s guide on which LED headlight brand is the best.
The XB Evo data points to a broader trend in aftermarket LED headlights: the gap between premium aftermarket headlights and factory equipment continues to widen. On every vehicle tested, the XB Evo significantly outperformed both stock halogen and stock LED headlights, often by factors of 2x to 3x. This performance gap, combined with DOT compliance, a 5-year warranty, and innovative features like the frost-free heating system, makes a strong case that the aftermarket headlight segment has matured to a point where the best aftermarket options genuinely exceed factory quality.
For consumers, the practical takeaway is straightforward. If you’re still running stock headlights on any of these vehicles and nighttime visibility is a concern, the XB Evo represents a substantial and measurable improvement. And if you’re running the original Morimoto XB headlights, the Evo delivers meaningful brightness gains (25% to 111% depending on the vehicle) along with a host of new features that the original lineup simply doesn’t offer.
The data doesn’t lie. The XB Evo is the brightest aftermarket headlight lineup currently available, and the comprehensive testing across five different vehicles proves it.

Frequently Asked Questions
How does the multi-point testing system work?
The system uses eight measurement points on a wall to evaluate headlight performance. Six points measure low beam characteristics and three points measure high beam, with some overlap. Light intensity in candela is recorded at each point and fed into a weighted formula that produces scores for distance zone, high beam, and width. These combine into an overall rating on a 1–10 scale. All measurements are taken from a single driver-side headlight under controlled conditions for consistency.
Why do some vehicles score lower than others with the same XB Evo projectors?
The headlight housing design, lens angle, and projector placement all significantly impact the final beam pattern. The Corvette C6, for example, has a very aggressive lens angle that limits what any projector can achieve, which is why its scores are lower than the trucks despite using similar projector technology. The scores reflect total system performance, not just projector capability.
Are these brightness scores relevant to real-world driving?
Yes. The multi-point testing system was designed specifically to measure the characteristics that matter most for nighttime driving safety: distance reach, center intensity, and lateral coverage. Higher scores correlate directly with better real-world visibility, wider peripheral illumination, and more comfortable long-distance night driving.
Is the supercharged driver safe to use daily?
The supercharged driver is designed for reliable daily use and does not void Morimoto’s 5-year warranty. The only consideration is that it pushes headlight intensity past DOT compliance limits, making the headlights technically for off-road use only in that configuration. Many owners use the supercharged driver daily and keep the stock driver as a backup. Swapping between drivers takes only a few minutes.
How do the XB Evo headlights compare to other aftermarket brands?
Across every vehicle where comprehensive shootout testing has been conducted (comparing 10–14 aftermarket options per vehicle), the Morimoto XB Evo has consistently scored highest. On the 09–18 Ram shootout, for example, the XB Evo outperformed every other aftermarket headlight available. The combination of bi-LED projectors, dedicated high beam assist, DOT compliance, and the optional supercharged driver creates a performance envelope that no other manufacturer has matched as of this writing.
