When it comes to building a serious retrofit, the projector you choose sets the ceiling for everything else in your headlight. We have spent countless hours on the bench comparing OEM HID low beam projectors, testing beam patterns against a wall, and installing them into all kinds of housings. In this HID projector retrofit comparison, we break down four of the most sought after donor projectors: the Lexus SC430, the Lexus RX-AFS, the Acura TSX, and the Honda S2000. Each one has its own strengths, price point, and quirks, and we want to help you pick the right one for your budget and your build.
Before we dig into each projector, it is worth understanding why a projector retrofit makes sense in the first place. A quality projector produces a clean, controlled beam with a defined cutoff line, which keeps light on the road where you need it and out of oncoming drivers’ eyes. That control is exactly what these OEM projectors are famous for, and it is why enthusiasts still hunt them down years after the cars they came in left the showroom.
Lexus SC430 Projectors: Rare, Expensive, and Supreme
Let’s start at the top of the food chain. The SC430 projectors are not recommended for budget conscious retrofitters. They are among the rarest of OEM projectors because of their low volume production, which unfortunately drives the price up and makes them tough to track down. It is a shame, because these are some of the most badass projectors ever made.
Similar to the S2000, the SC uses a wide reflector bowl and a curved shield to produce one supreme beam. What we appreciate most is that you can forget about the awkward ears that need to be trimmed off, something that adds work with other projectors. If you can get your hands on a set of these and throw a set of the right clear lenses on them, it is an investment in forward lighting you will not regret. The high price is real, but so is the payoff. For anyone chasing the absolute best beam pattern regardless of cost, the SC430 belongs on the short list.
Lexus RX-AFS Projectors: The Underrated Value Champ
Here is where things get interesting for the value minded builder. We think the Lexus RX-AFS projectors are one of the most underrated projectors out there. In stock form, they are restricted by the OEM Fresnel lens, so they are not all that exciting straight off the donor headlight.
The transformation happens with the TSXR clear lenses that come standard when purchased through The Retrofit Source. That single change flips the output 180 degrees. With a proper setup, the RX-AFS and TSXR combo produces a razor sharp cutoff line, a super wide beam pattern, and one of the smoothest light outputs in the game.
Tuned up, these will give you about 90 percent of the super exotic S2000 performance at half the price. That is bang for the buck in its purest form. If you want top tier results without the top tier spend, the RX-AFS is our recommendation. If you would rather skip the donor hunt entirely, we carry vehicle-specific projector retrofit kits that take the guesswork out of matching a projector to your car.
Acura TSX Projectors: The Universal Workhorse
If versatility is your priority, the Acura TSX projector is hard to beat. It is well respected for being one of the most universal designs for a dedicated low beam. With its short height, symmetrical bolt pattern, and lack of extra bulk, it will fit in a wide variety of applications with relative ease.
That compact footprint is exactly why we reach for the TSX so often when we are working in tight housings. When a headlight does not have much room to spare, a smaller projector with a friendly bolt pattern saves you from fabricating brackets or shaving down material. It is the kind of projector that just works across a huge range of builds.
On the optical side, the TSX comes standard with either OEM clear lenses or TSXR clear lenses, so you always get a sharp and colorful cutoff line right out of the box. Not to mention, it puts plenty of light on the road ahead. For custom builds where a vehicle-specific kit does not exist, pair the TSX with one of our universal projector retrofit kits to build exactly what you need.
Honda S2000 Projectors: The Ultra Wide Legend
Finally, we have the projector that everyone else gets compared to. The Honda S2000 projectors are known for their ultra wide beam pattern. Advanced optics combined with a stock clear lens and a curved cutoff shield make these one of the most respected projectors of all time.
There are trade offs, though. Despite being relatively big for a dedicated low beam projector, and despite needing much modification before it is retrofit ready, the S2000 rewards the effort with supreme performance. That combination of performance and rarity is why the S2000 stays expensive. Expect to pay 300 dollars or more for a set of these.
When we install a set of S2000 projectors, we plan for the extra work up front, from clearance considerations to the modifications needed to mount them cleanly. If you are chasing the widest possible spread of light and you have the budget and patience for the fabrication, the S2000 remains a benchmark. For most builders, though, the RX-AFS delivers most of that magic for a fraction of the cost.
How These Projectors Stack Up
So which projector wins the HID projector retrofit comparison? It depends on your goals. The SC430 offers a supreme beam but comes at a premium price and is genuinely hard to find. The S2000 gives you that legendary ultra wide pattern, but it is large, costly, and modification heavy. The RX-AFS with TSXR lenses is our value pick, delivering roughly 90 percent of S2000 performance at half the price. The TSX is the universal workhorse, ideal when fitment and flexibility matter most.
Whichever you choose, remember that the projector is only part of the equation. The right bulb, ballast, and lens all play into the final result. If you want a proven turnkey option, our Bi-Xenon FX-R Stage III retrofit kit pairs a strong projector platform with the supporting components to get you going. It is also worth browsing Morimoto’s HID and LED projector lineup to see how modern aftermarket projectors compare to these OEM classics, and checking out Headlight Revolution’s projector retrofit kits for additional install references and options.
Which Projector Should You Buy?
For budget conscious builders who still want serious output, the RX-AFS is the clear winner in our book. For universal fitment across a wide range of housings, the TSX is the smart, compact choice. If money and rarity are no object and you want the widest beam or the most exotic pedigree, the S2000 and SC430 are your endgame projectors. Every one of these has earned its reputation on the bench and on the road, and we have tested them all so you can build with confidence.
Frequently Asked Questions

They are among the rarest OEM projectors due to low volume production, which makes them expensive and hard to find, even though they produce one of the best beams available.
What makes the Lexus RX-AFS projector a good value?
When paired with TSXR clear lenses (standard when purchased through The Retrofit Source), the RX-AFS delivers a razor sharp cutoff, wide beam, and smooth output, reaching about 90 percent of S2000 performance at half the price.
Why is the Acura TSX projector considered so versatile?
Its short height, symmetrical bolt pattern, and lack of extra bulk let it fit a wide variety of retrofit applications with relative ease.
What lens options come standard with the TSX projector?
TSX projectors come standard with either OEM clear lenses or TSXR clear lenses, both delivering a sharp, colorful cutoff line.
What are the drawbacks of the Honda S2000 projector?
The S2000 projector is relatively large for a dedicated low beam, requires significant modification to be retrofit ready, and typically costs 300 dollars or more due to its performance and rarity.
