The first commercial halogen lamp was developed around 1959. In most applications they're easy to recognize due to the high heat and orange light output. They also have a lower life span with lower light output per watt. Prior to recent years technology was not advanced enough to use LEDs to replace headlight bulbs. The low output made it simply dangerous. OLM's Alpha HDs continue and build upon past generation OLM bulbs and provide usable light output with a beautiful, premium look.
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: This is for vehicles NOT equipped with LED low beams or HID low beams.
Warranty: 1 year IP rating: IP67 Minimum Light Output: 3520 lumens per pair Maximum Light Output: 4000 lumens per pair Approximate Wattage: 20-25 watts each
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.

Install the LED bulb in the socket in the same manner as the stock bulb.
For the driver's side, it is recommended that you loosen the battery tie down and move the battery a little to gain access to this bulb. Repeat the same steps above. Once you are complete, test the lights. If they work properly, tighten everything back down and reassemble the airbox.
NOTE: When using the allen key, do not overtighten screws.
I bought these lights as an upgrade to the ugly stock halogens. The install and adjustment was very easy and only took about 15 minutes if that. What a gigantic difference! The lighting is greatly improved and the color is perfectly white. Everything is lit up so well down the road. Next step is upgrading the foglights
OEM Alpha HD bulbs

Halogens make me sad.
By EricAugust 28, 2017
I was a bit concerned about installing LEDs in the OEM headlight housings that were designed for halogens. These bulbs are a good upgrade. The cutoff is more sharp than the stock bulbs, but the 5500k lights up the road much better. It was necessary to remove the gaskets that come with them and use the ones from the original bulbs. Ordering the matching high beams today.
Great Headlight Bulbs

I got these bulbs to replace the OEM halogen bulbs. They are certainly bright and outline the road perfectly! HID might be brighter, but I don't particularly like HID lights anyway.
Installation was easy enough but getting them to fit properly took a little doing. You have to twist them slightly to fit into the grooves, just make sure you don't twist too hard.
Overall extremely bright bulb, much brighter than OEM. I would recommend these to anyone looking to update the bulbs and upgrade the style of the WRX.

Not quite as bright as the the HID/LED headlights, but it's the runner up. Much easier to install though.

These headlights are a lot brighter than the stock ones. The ultra white lights look really clean.
