Only one headlight works

It is possible that even after replacing the bulb, the headlight doesn't work. Common problems that cause this issue include:

  • Damaged wiring inside the headlight unit.
  • Damaged wiring harness taking power to the headlight.
  • A corroded connector at the headlight
  • Blown fuse

Use a digital multimeter to check the voltage at the headlight connector.

Unplug the wire harness from the headlight. Identify the wires that provide power to the burned bulb. The negative wire will be either black or brown. The positive you will have to find out. Set your digital multimeter to voltage, turn on the headlight, and measure.

The problem with the low beams being out but not the high beams is a wiring issue that I'm having to most of the time it's not the bulb. And to replace the driver side headlight you need to take out the battery no other way

I'm dealing with The Exact Situation Rite Now. SMH. Ever find out what the Problem was??

Thank you so much! Hubby doesn't do anything for my car.

This video shows how to replace the bulb on the passengers side (easy one). I need to replace the bulb on the drivers side. This looks impossible to do yourself. There's about 1.5” of room between it and the battery. Any ideas on how to do the drivers side yourself???? Thanks.

This does not seem to apply to Optima SXL.. The bulb does not come out of the assembly. Going to take it to the dealer.

Did anyone figure this out?

On a 2016 KIA Optima Hybrid there's very little space to change the bulb

Visitor

My lowbeam is out but not the high beam. Replaced the bulb but it still doesn't work

Visitor

Remove the battery from the drivers' side. This allows more space to turn the cover and replace.

The low beam light was out on my Kia optima. It looks very easy to replace so I will try this on the weekend. Thanks for the video.

Go in from underneath, by gently pulling away the splash guard for the driver side front tire. Plenty of room underneath.
