This problem isn't on my truck. It's on my mom's Subaru Outback but the knowledge base here is superior to any other forum I've ever been on so I hope y'all don't mind I ask.
The left turn signal blinks faster than normal. It initially blinked slower. When I went out to have her show me, it was blinking faster. The right one still blinks at normal speed. I thought there was only one flasher for any vehicle.
I was just wondering if anyone would know why would one side blink faster than the other?
Found one where there was a thread on this exact problem. Turns out the TS bulb is a dual filament bulb and the car is rigged so that when one filament goes the other is used. That's why it blinks faster. It was probably blinking slower because the filament was about to blow and then when it blew it now used the other filament which made it speed up. Pretty cool design isn't it. Instead of not knowing your bulb is broke until someone tells you, the car lets you know you need a new bulb and it still works at the same time.
Yeah, I know. Bulb is what I initially thought. But I thought one of them wouldn't be working. The fact that it was working is what threw me. I've never heard of one that still works when it's bad. I guess anything's possible til you know the facts.
It's not completely straightened out yet. I did find the forum and thread but haven't actually done the work. So until it's done, we won't know for sure. Its good to have a good head start though.

Glad to hear that you found out the problem.
That sounds pretty tricky man!
I never do that. I don't know what it is about bulbs but the lifetimes on bulbs of the same type are never similar. At least in my experience. If you go to snopes.com there's a story about a light bulb in some California fire station that's been burning since 1901. So I never throw out a working bulb. Replacements aren't cheap anymore. You go anywhere to get one and you have to buy two and it's $4-5 for the pair. They used to be pennies. I grab them out of cars when I go to the U-pull it. Especially headlight bulbs. I've got a whole drawer full.
