Rear Turn Signal LEDs for 2004-2016 Subaru WRX (pair)
From the factory, rear turn signal bulbs are powered by standard incandescent lights that light up white in color, and cast light through your red or amber tail light lens. This results in a washed-out color.
Newer luxury vehicles are using LEDs for turn signals, because LEDs offer a crisp, instant on/off function, increased brightness, and true, vibrant color. By replacing the bulbs in your vehicle, you can achieve this modern look!
The installation is 100% plug-and-play, just replace your factory bulb. The bulb may blink faster since it uses less power, and your vehicle thinks the bulb is out- to fix this, please see "hyperblinking" section below.
HP48: This bulb is non-polar, CK compatible, with 48 Epistar 3014 LED chips. Thanks to the cap on the top, the light from this High Power Bulb is shined backwards and away from the bulb, not straight out. This means the output is excellent, because it uses the vehicle's housing completely, which then shines the light much more uniformly.
HP11: Four side-firing 1.5W-rated Osram LED chips, and one 5W-rated LED chip on top, which is projected by a lens for maximum effective brightness. The bulb is housed in a machined aluminum casing, which provides superior heat diffusion for long life.
XP80: Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.
Fitment. All three bulbs use a quality inject-molded 7440 terminal, with a full-size base connector and proper pin alignment, designed for exact replacement of your factory 7440 bulb.
Included in your order is TWO BULBS.
These LEDs illuminate in a crisp, bright, amber or red hue. Choose the color of your rear turn signal lens.
Diode Dynamics offers several brightness options so you can choose what fits you best. These options are listed by the design and the lumen output of each bulb:
HP48: Slightly lower brightness than OEM bulbs, but still provides the crisp, modern instant on/off of LED technology.
HP11: Slightly higher brightness than OEM bulbs.
XP80: Much brighter than OEM bulbs. These are bright!
Lumens: BUYER BEWARE! Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum.
These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures. Please click here to learn more about LED brightness measurement.
