Left turn signal blinking twice as fast. All lights ok.

For the past 2 months my left turn signal has been blinking super fast. All my lights are on though. Does this mean one is on its way out? And how would I know which one needs to be replaced Speed Test https://vidmate.bid/ ?

Or is it some sort of electrical problem?

It could be a loose or defective light bukb. I would start by replacing the fast blinking light first.

bad blinker bulb

It's usually a bad bulb. That, or someone thought it would be cool (for whatever reason) to replace a standard bulb with an LED replacement. There could be another issue, but those are most common.

On one of other trucks, turned out to be a relay switch in the fuse box

No relays. All the stuff is computer controlled now.

Yeah, well.... I'm old. Those trucks weren't even made in this century.
