What Lighting System Does the 2019 Kia Niro Have?

The 2019 Kia Niro features an extensive lighting system with 13 bulb positions. It uses halogen technology with a single HID-D8S LED dual-filament bulb handling both low and high beams. The Niro has been available from 2017 to 2021, and the 2019 model falls in the mid-generation years.

Can You Put LED Bulbs in a 2019 Kia Niro?

Upgrading the 2019 Kia Niro to LED headlights is straightforward since it uses a single HID-D8S LED dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a HID-D8S LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a H8 LED LED bulb provides a clean white output that pairs well with LED headlights.

How to Replace Bulbs on a 2019 Kia Niro

To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. On the 2019 Niro, you will likely encounter rubber dust covers behind the headlight housing. These pull off by hand or unscrew depending on the design. Allow about 15 to 20 minutes per side. When installing the new bulb, avoid touching the glass with bare fingers. Skin oils create hot spots that shorten bulb life. Wear clean gloves or handle the bulb by its plastic base only. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the H8 LED fog light socket.

How Long Do 2019 Kia Niro Headlight Bulbs Last?

Standard halogen headlights on the 2019 Kia Niro have an expected lifespan of 500 to 1,000 hours, which works out to roughly 2 to 3 years of normal use. Signs of a failing halogen bulb include noticeably dimmer output, a yellowish tint compared to the other headlight, or intermittent flickering. At 7 years old, the original bulbs on your Niro are likely overdue for replacement. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.

What Bulbs Are Compatible with the 2019 Kia Niro?

The D8S low beam bulb on the 2019 Kia Niro is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact D8S size. Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.

2019 Kia Niro Headlight FAQ

The 2019 Kia Niro uses a HID-D8S LED bulb for the low beam headlights. We recommend upgrading to LED for better visibility.

The high beam bulb size for the 2019 Kia Niro is HID-D8S LED.

The 2019 Kia Niro uses a single bulb (dual filament) headlight system. This means one bulb controls both high and low beams.

Yes, the 2019 Kia Niro comes with standard halogen bulbs from the factory, but they can be upgraded to LED. You will need a HID-D8S LED LED conversion kit for the low beams.

Yes, the 2019 Kia Niro takes a H8 LED bulb for the fog light position.

Turn off the vehicle and open the hood. Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old HID-D8S LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble. The whole process typically takes 10 to 30 minutes per side depending on accessibility.

LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state. Many states allow LED retrofits as long as the beam pattern meets DOT standards. For the best legal compliance, choose a DOT-approved HID-D8S LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

A pair of halogen HID-D8S LED bulbs costs $15 to $40, while LED conversion kits run $25 to $60 per pair. If you have a shop do the work, expect an additional $20 to $50 in labor per bulb. Replacing them yourself at home saves the labor cost and usually takes under 30 minutes.

Halogen bulbs produce a warm yellow light (around 3200K), last 500 to 1000 hours, and draw more power. LED bulbs emit a brighter white light (5000-6000K), last 25,000+ hours, and use less energy. LED upgrades for the HID-D8S LED position are available as direct plug-and-play replacements.

Did Kia Niro Bulb Sizes Change Over the Years?

The Kia Niro has maintained consistent bulb sizes across all model years from 2017 to 2021. The low beam has used a HID-D8S LED bulb throughout, which means replacement parts and LED upgrade kits are widely available and well-tested for this model.
