: My turn signal bulb keeps blowing—could this be a wiring issue in my Elantra?

The front left turn signal bulb on my 2016 Hyundai Elantra has gone out three times in the past year. Im wondering if this is more than just a bad bulb. Could a faulty socket o r corroded connection be to blame?

Answer:
Yes, if a turn signal bulb keeps blowing, especially the same one repeatedly, it could be caused by:

Loose o r corroded socket connections

Water intrusion into the light housing

Short circuit o r exposed wiring

Overvoltage in the electrical system

Start by inspecting the socket and wiring for corrosion, moisture, o r melting. Use dielectric grease on the new bulb socket to protect against moisture. If the issue persists, a mechanic can perform a voltage and continuity check to detect deeper electrical issues.
