turn signal bulbs burning out fast

I've replaced my turn signal bulbs three times in two weeks and it's not cheap! I don't understand why they keep burning out so fast. What could be the problem?

Dang, three times in two weeks? that's brutal, bulbs shouldn't be going out that fast. Could probably be a voltage issue, like the circuit is getting overpowered and frying them early or maybe moisture in the housing is messing with the contacts? while at that maybe also check the socket for corrosion or loose fit too cos sometimes a janky connection can cause them to heat up more than they should.
 
Frequent bulb burnouts usually happen if the voltage is too high, possibly due to a faulty flasher relay or a bad ground connection. I recommend checking the wiring and connections, and if everything looks solid, consider testing the relay or replacing it with a higher quality one to prevent further issues.
 
They could be killed too soon by a voltage spike, excessive vibration, or a damaged socket (corrosion or loose fit). It happened to me once, I changed to an LED, cleaned the socket, and checked the ground. The issue has been resolved

I have a 2022 Sequoia Platinum and my rear turn signal bulbs went out twice last year. I haven't looked at the relay yet but do factory ones go bad early? Also, if I switch to LED bulbs, will that help the system or cause problems if I don't use the right resistors?
