OEM Subaru headlight replacement parts
Car manufacturers produce Original Equipment Manufacturer (OEM) replacement parts suited for their vehicles. These “Genuine” components replace stock parts on a one-for-one basis, fitting in the same spaces and using the same attachment points. They deliver the same performance and return the vehicle to tiptop shape.
Subaru of America builds OEM headlights and other Genuine replacement parts for various vehicle models. You can only get these products at Subaru dealerships and retail stores partnered with the company.
Subaru enthusiasts who own discontinued models, like the Outback Sport and Tribeca, may find it more difficult to get their hands on OEM replacements for bad or failing parts as time goes by. Subaru no longer supports those models and only made so many replacement parts before halting production.
Technical Service Bulletin involving OEM Subaru WRX headlights
Some OEM parts could come with flaws that slip through the original manufacturer’s quality control and only crop up on the road.
In August 2018, Subaru issued TSB #07-139-18R for the 2018 Subaru WRX. The TSB warned how the flawed inner lens of some 2018 WRXs could concentrate sunlight onto the lens’ extension portion during certain conditions. The resulting heat could melt the lens and affect the light beam projected by the headlight.
Once Subaru caught wind of the flaw, it came up with a new headlight assembly fitted with a heat-resistant shade to protect the lens extension. New-built 2018 WRXs received the improved headlights while owners of affected vehicles could bring their ride to the nearest Subaru dealer and get the defective lens replaced.
OE Subaru headlight parts
When a replacement part comes from a manufacturer that didn’t make the vehicle and has no connection to the original car maker, they are Original Equipment (OE) parts. These aftermarket components offer more or less the same performance as their OEM counterparts. Most OE parts fit in the same location as the stock part and take advantage of existing attachment points.
Many OE manufacturers offer performance parts that work better than OEM replacement parts or come with unique features absent on stock parts. For example, if your stock Subaru WRX headlights don’t shine brightly enough for your liking and safety, you can install OEM headlights with brighter LED or xenon arc bulbs.
How much does a Subaru headlight cost?
An OE replacement Subaru headlight can go for anywhere between $23 and $680. Its price varies depending on its manufacturer, the presence or absence of light bulbs, its light source, and the quantity sold. You can get individual headlights, pairs, or exterior vehicle light replacement kits with other parts like corner lights or turn signal lights.

- What 's the difference between conventional halogen systems and Xenon/HID systems?
Xenon/HID systems and halogen systems go about light creation in different ways in terms of principles and techniques. HID bulbs are three times more powerful than halogen lights because of it usage of xenon gas and halide salts contained within a tiny capsule. In contrast, halogen headlights utilize the traditional filament method of creating light that 's been used since the invention of the incandescent bulb. Its light source is the filament that 's made bright hot by letting basic ohm resistance pass through it. Your Subaru 's 12-volt system is enough to run a halogen-based headlight system. Meanwhile, HID bulbs require a ballast setup in order to get a precise supply of high voltage power.
- What are the three types of headlight for your Subaru?
The three types of headlight available to your Subaru include ellipsoidal, freeform, and parabolic headlights. Ellipsoidal headlights work like projectors (so they 're also known as projector headlights). They are horizontally cut off at the first focal point prior to the beam getting projected back again via a curved lens. Freeform headlights have a front lens that 's clear, so they lack the reflector found in parabolic headlights. Finally, parabolic headlights (which are categorized as reflector design headlights along with freeform headlights) make use of a parabolic reflector to focus and control its light source 's beam. It 's capable of dispersing light to every side thanks to its front glass.
- What are the differences between reflector and projector headlight designs?
The reflector design involves focusing the light source directly into a beam of sorts (just like how a flashlight would work) so you 'd use less power to get a brighter result. Meanwhile, projector designs go about light projection in a less direct and more roundabout manner (just like the projectors used in schools and offices). Additionally, projectors have a sharper cutoff compared to reflectors. Freeform reflector designs are the most power efficient type of headlight design at 45%. Meanwhile, second generation ellipsoidals are about 52% power efficient (first generation ellipsoidals were only 36% efficient). Finally, parabolic reflectors are the least efficient at 27% efficiency.
- How does a Bi-Xenon system work?
A Bi-Xenon system for the Subaru normally uses a high-low beam coming from the same HID bulb. A traditional HID low beam/Halogen high beam setup isn 't capable of this feat; it requires separate bulbs in order to achieve the high-low beam effect, making it more expensive to use. The Bi-Xenon bulb can make use of either the projector or reflector design, although the projector design is the simplest one available. On the other hand, Hella is a Bi-Xenon variant with a moveable shield from inside a projector setup that makes use of a two-position servo motor or a spring-loaded solenoid.
- What is the beam difference between DOT, JDM, ECE, and harmonized headlights?
DOT headlights follow the headlight standards of the United States of America. They allow increased illumination of overhead signs and higher glare levels. However, their maximum allowed illumination rating is 28,000 candela. JDM or Japanese-standard headlights make use of lights for left-side driving only.ECE headlights follow the headlight standards of Europe. They 're all about sharp horizontal cutoffs and lower glare levels. They also require a maximum allowed illumination rating of 38,000 candela. Finally, harmonized headlights could be used under ECE and DOT guidelines. However, a real ECE headlight will always have a higher allowable candela compared to a DOT headlight.
