Part #: OLM-7440-AM x2. The factory bulb is fully tinted orange, which makes the housing turn orange too. In contrast, this OLM LED bulb has much less color overall, making the color in the housing less obvious. Turn signals are vital, and this high - power LED bulb is a great replacement for the stock halogen bulb. It's bright enough to ensure safety. Note: The bulb is sold individually.

Using this OLM LED front turn signal bulb is easy. Just remove the old factory bulb from your Subaru WRX 2015 - 2021 or STI 2015 - 2021 and replace it with this new LED bulb. When handling the bulb, make sure your hands are clean to avoid leaving any dirt or oil on it. Also, ensure the power is off before installation to prevent any electrical issues. As for maintenance, it doesn't require much. Just check regularly to see if the bulb is working properly. If you notice any dimness or flickering, it might be time to replace it. And remember, this bulb is sold individually, so if you need to replace both bulbs, you'll have to buy two.
