We think these are totally amazing. See, the stock front turn signal is also your marker light. And it's amber. We'd like to replace it with cool-looking hyper-white LEDs, but it would be illegal to not have an amber turn signal.
Enter these awesome replacement bulbs. They use a matrix of 60 surface-mount technology high-powered LEDs in TWO colors -- hyper white AND amber. They light up hyper white when the car lights are on, then when the turn signal or hazard lights illuminate, they light up AMBER. Turn off the turn signal, and they revert to hyper white. It's all completely automatic.
What'll they think of next?
Set of two bulbs. Fits 2008+ Impreza (all including WRX and WRX STI). Note! Outside the U.S., some countries have separate running and turn signal lamps. This bulb will not fit those lamp housings.
LED Turn Signal FlasherLEDs have a lower resistance than regular bulbs, which may cause your turn signals to blink extra-fast. If you don't want this, install this replacement blinker unit, which is designed to work with LEDs.
You only need one flasher per car. Also, this flasher works with two LED turn signals OR four, so it would still work if you happen to ever install LEDs in the rear of your car too.
Install note: To find the turn signal blinker module, turn on your hazard lights and stick your head down under the driver's side footwell. You'll hear it clicking away. To install the new module, just unclip the wiring harness from the old module and plug it in to the new one. Zip-tie the new module safely out of the way. We suggest not trying to remove the old module; it hardly weighs anything and it's hard to get it out of there.
