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 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.
The video below shows the standard bulbs -- see our second video below for a comparison of the two types.
What'll they think of next?
Easy to install -- remove the battery on one side, and the airbox on the other side, to reach the back of the bulb socket, then just swap in the new bulbs.
NOTE! LED blinker bulbs will cause your turn signal/hazard flasher to blink extra-fast. Get the special LED-capable blinker relay below to avoid that problem.
The standard bulbs have high-tech surface-mount LED drivers. The Mega-bright bulbs have Mega-powerful 0.5-watt LED drivers, and are nearly TWICE as bright as the standard bulbs.
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 Blinker ModuleLEDs have a different resistance than regular bulbs, which will 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 blinker module per car. Also, this blinker module 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.
Note that after installation of this blinker module, your lights may not flash, or they may only flash very briefly, when you trigger the remote locking. This is normal.
This flasher unit fits 2008+ WRX/STI. It does NOT fit earlier Subaru cars.
