Daytime Running Lights: The vast majority of other LED headlight bulbs are powered by drivers that flicker, flash, or simply wont turn on when powered by a low voltage DRL (daytime running light) circuit. The 2Stroke works like a charm here, behaving as it should and simply running at a lower intensity. A simple, smart, compact voltage regulator that's protected inside of a sealed aluminum housing drives the 2Stroke's CREE XHP50 LED chips at varying degrees of intensity depending on the input voltage. Max output is reached at 10V.
NOTE: Not for use in low voltage high/low beam DRL applications.
Pretty Cool: Heat management is crucial for lumen maintenance and reliability. The 2Stroke bulb's internally opposed 1.5mm copper boards extract as much heat as possible from the area surrounding the LED chips and transfers it to the radiator at the back of the bulb. Yea yea, copper stuff and fans, seen that before...The key here though is that the 2Stroke's copper core has almost 3x more surface area than anything else, and its fan is A) Mounted sideways so that it not only sucks cool air but also blows hot air out. B) It's a magnetic levitating unit, so there's no ball bearing to seize up and eventually fail.
Size Matters: Due to the extra depth of most LED bulbs, they won't fit inside headlights with solid plastic rear housing caps. The 2Stroke is no different, but they come with specially designed housing cap extensions to solve that common problem. If the original halogen bulb is exposed it's not a problem, but if its internally wired and capped off: you would not be able to close the headlight back up without these caps. They look pretty cool too, with the embossed "2S" logo molded into the back.
Fits all 2004-2014 Subaru WRX and WRX STI high beam.
