OLM Hikari Series LED Headlights for WRX and STI

The stock halogen headlights on the WRX and STI are one of the most common complaints in the community. The output is dim. The color temperature is yellow. The throw at speed does not match what the car is capable of. For a platform built around performance, the factory lighting feels like an afterthought.

For Subaru WRX and Subaru STI owners who want a proper LED upgrade without cutting wiring or retrofitting bulbs, the OLM Hikari Series is the purpose-built answer.

What Is Wrong With the Stock WRX and STI Headlights

The factory halogen headlights on the 2015 to 2021 WRX and 2015 to 2017 STI were not designed with performance driving in mind. The output is adequate for city driving. At highway speeds, beam throw and peripheral visibility fall short. The warm yellow tone of halogen also ages the look of the car compared to modern LED setups.

A bulb swap helps slightly but does not solve the core problem. Halogen housings are designed for halogen output. Dropping an LED bulb into a housing not built for it produces an inconsistent beam pattern. It can also create glare for oncoming drivers. A full headlight assembly upgrade is the proper solution.

What the OLM Hikari Series Actually Is

The OLM Hikari Series is a complete LED headlight assembly replacement. It replaces the entire headlight unit on both sides. The output is significantly improved over stock. The color temperature is a clean white. The beam pattern is designed for the housing from the ground up.

Installation is plug and play on compatible trims. No wiring modifications, no cutting, no retrofitting required. The Hikari bolts into the factory location and connects to the existing harness. The OLM Hikari Series LED headlights for WRX and STI are available now for compatible model years.

Who the Hikari Is For and Who It Is Not For

Compatibility matters here. It is worth being direct before buying.

The Hikari fits the 2015 to 2017 WRX, the 2015 to 2017 STI, and the 2018 to 2021 WRX Base and Premium. These are the trims that came with halogen headlights from the factory.

The Hikari does not fit the 2018 and newer WRX Limited or any 2018 and newer STI. Those trims came with factory LEDs already. It also does not fit the 2022 and newer WRX. That is a different generation with a different housing entirely. Check your trim before buying.

OLM Hikari vs a Bulb Swap: What Is the Difference

A bulb swap is the cheaper option. The problem is that halogen housings are calibrated for halogen output. An LED bulb in a halogen housing scatters light rather than projecting it cleanly. The beam pattern suffers. Glare for other drivers is a real issue.

The Hikari is a full assembly built around LED output from the ground up. The projector housing, lens, and light source are designed to work together. The beam pattern is consistent and the install requires no workarounds. OLM engineers these assemblies specifically for the WRX and STI platform, which shows in the fitment and output quality.

How the Hikari Fits Into a Broader Exterior Build

The headlights are the front half of the exterior lighting story. For owners who want a complete front-to-rear setup, the Hikari pairs naturally with OLM’s tail light lineup. The Evolution tail lights and NB+R at the rear create a cohesive look that matches the Hikari at the front. Our post on OLM tail lights for WRX and STI covers how those two products work together.

Is the OLM Hikari Worth It

For WRX and STI owners on compatible trims who drive at night regularly, yes. The stock halogen output is a genuine limitation. The Hikari addresses both visibility and aesthetics with a clean plug-and-play install.

For owners not on a compatible trim, the Hikari is not the right fit. But for anyone on a 2015 to 2021 WRX Base or Premium, or a 2015 to 2017 STI, the Hikari Series headlights are the cleanest upgrade available for the front end.
