The 19w bulb from the factory produces an orange light and only has enough intensity to light up the road a few feet ahead.
The typical LED bulb that you see looks great in the reflector when viewing the vehicle, but they don't really put out much usable light. Even less than the 19w stock bulb.
OLM has a bulb which has a higher output and whiter light. Most people will not use fog lights for the sole purpose of navigating through fog. Many areas are not even prone to fog. A large percentage of users can benefit from a driving light vs a fog light. Placing more light on the ground during normal driving can increase a driver's situation awareness as well as those around them.
The base of the light is adjustable so you change the focal length resulting in the best output. The heat sink is also reversible in case your application demands the bulb to conform to a different profile for proper fitting.
NOTE: If your WRX / STI was made for the Australian market, we cannot recommend this bulb. The design of the fog light housing for this market is different. The housing contains an additional P13W bulb which may interfere with this one.
Crosstrek owners WITH steering response fog lights (SRF) can use this bulb. However, for Crosstrek owners WITHOUT these, you can purchase our lamp assemblies which will modify your light to an H11 socket (ie Glass replacement fog light housings).

SAY NO TO HIDs
HIDs are great for certain applications. A small, thin plastic housing is NOT one of them.
This controlled testing shows the results of a 35w HID kit mounted inside the stock 2015 WRX / STI fog light housing.
In the picture below, you can see the extent of the damage on the inside of the casing.
For this application, the OLM Alpha LED fog light bulb is a great solution. It also results in much less glare than an HID kit.
Phillips Z ES LED Chip
LUXEON Z ES is a high-power 1.6mm x 2.0mm LED that enables never before seen color consistency, luminance, flux density and design flexibility for lighting solutions because it's the first ever 1-step MacAdam Ellipse warm white LED. LUXEON Z ES is undomed, a feature that provides un-matched optical flexibility for precise beam angle control. Tested and binned at application conditions, 85°C, the LUXEON Z ES emitters are an ideal choice for indoor and outdoor light sources requiring superior beam angles and superior results.
The OLM Alpha HD setup uses 8 of these precision chips to make for a competent replacement for OEM halogen bulbs.
Efficiency is high on this bulb's list of positive traits. As seen in the picture, at 13.5V this bulb is only drawing 1.5 amps. Power is 20.25W at this temperature.
Tuned Light Output
Straight out of the box, the OLM Alpha HD offer superior total light output and uniform color. With the adjustable base, you can rotate the light as required to change the focal length and aim of the LED chips. This ensures that the setup results in usable light which will help guide you through the hours of dusk and night.
The heatsink is also reversible if your application demands more space towards the rear of the bulb.
Plug and Play Installation
Installation of the H11 OLM Alpha HDs is extremely simple. If the socket fits, that's where it goes! The LED driver to bulb connections come with rubber seals to make sure the connection remains watertight.
The kit comes with an allen wrench for modifying the focal length of the bulb. Simply loosen the screw and rotate the base until it is in the desire position. Once you are satisfied with your setup, tighten it back down. Do not overtighten.
The allen key can also be used on the heatsink to reverse the orientation to create extra space towards the rear of the bulb.

I knew as soon as I took the first drive in my WRX Limited that the fog lights were a disappointment. The OEM fog lights are dull and offer little-no noticeable light output next to my LED projectors. I installed these lights as a replacement for the OEM fog lights and they're infinitely better!! I'm am very VERY pleased with them, and installation was under 5 minutes for both. All you have to do is peel back the underlining by the fog light, unscrew the OEM light, disconnect them and then connect the ALPHA HD bulbs and secure them in. I was amazed at how simple the process was. HIGHLY recommend this upgrade!

I really dislike the stock color of the fog lights and I knew I wanted to change them ASAP and I was skeptical at first as to how bright these are and their color. Turns out these are incredible! I absolutely love the color match with my other alpha hd led high beams and my JDM sequential light bezels!! You can tell a huge difference between these and the OEM bulbs, these are without a doubt way brighter and a much cleaner bright white color instead of the faded yellow. If you have fogs and you want that nice modern style light, look no further! They are worth the price! Plus, they're very very easy to install, took maybe 20-30 minutes tops.

Great look. Well worth the money ! Looks great on my STI
Perfect Fit and Match

Bought these to match the fog lights with the stock HID running lights on my '15 Limited WRX. The install was a breeze - I suggest installing via the splash plate underneath the front of the car and not through the wheel well. The color and warmth matches up perfectly.

I have these installed on both my headlights and fog lights and I can see everything now. I used to hate driving at night because I thought I had night vision problems. Turns out I just need the right bulbs. I highly recommend!

Very bright bulbs. No complaints. Had them for a couple weeks. I think the stock housing is letting them down. I may be wrong but I believe the stock housings isn't allowing for a wider dispersion of light which is counter productive for a fog. I might make that my next upgrade.
So bright! Dual purpose!

I am currently running these for both my fog lights and my headlights. They look incredible and the amount of light that they put out is insane. Very clean install. Plug and Play and no issues so far.
