Hey all, figured id get the quickest response here

04 wrx, stock headlights, sylvania bulbs, they've been in my car for at least a year..

just now I turned my car on, turned my headlights (low beam) on, I saw both flicker really quick and then die

All other lights (high beam, parking lights, taillights) are working fine, pulled the low beam bulbs and the filaments were busted, checked a couple fuses that were labeled for lights and they were all good

Googled it and came back with possible relay problems, or battery/voltage...any ideas?

Just don't want to buy new bulbs and have them die instantly

TIA

 

Check your fuses Brian. It could be as simple as that.

 

Maybe I missed one, but there are two labeled left headlight and right headlight...even pulled a few others and all were good

 

Same **** happened in my GC years ago. Bulbs were new/not blown, fuses were fine. Highs and signals would work, but not lows. The switch was the culprit.

 

My bulbs both blew out though, filaments busted...they flickered almost like an HID bulb would and then cut out

Which switch and how to fix it?

 

No one?

 

It is hard to diagnose electrical gremlins through posts.

Could just be a fluke that they blew at the same time. I say buy three bulbs use one bulb to test the sockets, if it blows the first one delve deeper with your diagnostics . If it works in both hook up the other one and put one in your glove box as a spare.

If they are blown than it is most likely not a bad switch.

Do you have a multimeter? If not I have an old one you can have. Seems I get one for x-mass every couple years.

 

My advice... Go to Walmart. Buy 2 new bulbs. They cost about $4.75 a piece. Put them in. See if it happens again.

It's possible that (since you were a good boy) you replaced them at the same time and they were tired. When you started it there was a voltage spike that blew them.

I'd toss 2 new bulbs in there and see if it happens again before you panic.
