Flashing Oil and Brake Lights 2012 Subaru Outback

Problem: AT Oil Temp and Brake lights flashing, while the TCS light is solid.

Solution: Turns out that both of my brake lights were out (because I didn’t use gloves while replacing the bulbs a few months ago). Replaced them and haven’t had any issues since (it has been 5 days).

Difficulty: Super easy.

I was driving home from work on Friday when all of the sudden (ironically the exact same place where I got my bad flat last year) the lights on my dash light up! I was freaking OUT. The brake light and AT Oil Temp lights were blinking like crazy and the Traction Control light was solid. Those were the only lights and even though I was freaking out, my car was driving perfectly fine, no weird smells or noises. The check engine light wasn’t lit up. My mind kept going through all the worst case scenarios and reasonings. I’d literally just gotten my car back from the shop after a very expensive brake and rotor replacement and I could only deduce that had something to do with it, but how? Everything felt fine. It was then that I remembered that at a light a few minutes earlier, a nice man in an old car told me that both of my brake lights were out. That kept niggling around in my head, but given that I had a while to go to get back home, I’m still anxiety-ridden that my car was about to erupt into flames or stop moving randomly or have smoke billowing from all over. I manage to stop by Advanced Auto Parts to ask for a code read and the dude was looking at it all stumped. No codes, nothing wrong under the hood. I bought some brake lights from him and got back into my car. Lights were off now and I kept bracing for them to come back on, which finally did happen about 10 minutes later, but by then my car seemed fine so I felt only mildly nervous driving home.

Safely there, I furious search the internet and only on some random forum page 15 minutes later on a similar but not quite topic, I find another situation like mine, except he replaced both of his brake lights and it was fine. I was like, huh, coincidence? Not too likely. As it turns out, that was the answer. Replacing the burned out brake lights. GO figure it was that easy. Make sure you use gloves when you replace those bulbs, kids. Otherwise the oil from your fingers sit on the bulb, heat up and BOOM. Burnout.

DIY: Replacing 2012 Subaru Outback Brake Light Bulb

03/22/2018

One of my brake lights went out, so I needed to replace it.

Difficulty: Very Easy!

Time: 5-10 minutes

Tools: Philips head screwdriver(s), replacement bulb, gloves (important!!) and optional ratcheting socket wrench

Here we go!

  1. Open the trunk and you see this:

2. Use the screwdriver to unscrew, and you’ll feel it click twice-ish

3. It’ll pop out like this, so carefully twist/pull it and the ring out. Repeat with the 2nd one

4. Carefully insert a thin screwdriver or pry tool around the side closest to the outside and gently loosen the part until it pops out

5. Now you see this

6. Take your bigger screw driver and locate these screws. Mine happened to be stripped from last time and replaced WAY too tightly, so I needed the socket wrench to help

8. And with a little pull towards you, the whole housing comes off!

9. The one we need today is the middle grey one where the lines connect. Just a little twist and off it comes

10. There’s the old bulb. Just give it a tug and replace it with the new bulb

11. New bulb! *Important* Wear gloves before putting the new bulb in!! So, everything now goes backwards. Put the bulb in and twist until it locks in place

12. Replace the brake housing. There are two tabs on the side where the housing will slide into.

13. Slide it in…and…

14. …push! It’ll click into place.

15. Do everything backwards and VOILA!!!

All done. Make sure the light works, but that’s all there is to it!!!

This is what happens, by the way, when you touch the bulbs with your bare hands. The upper bulb has a burned spot where the oil from my finger got, heated up, and *poof* burned out the bulb.
