What Lighting System Does the 2017 Infiniti QX30 Have?

The 2017 Infiniti QX30 features an extensive lighting system with 11 bulb positions. It uses halogen technology with a single H9 LED dual-filament bulb handling both low and high beams. The QX30 has been available from 2017 to 2019, and the 2017 model falls in the early-generation years.

Can You Put LED Bulbs in a 2017 Infiniti QX30?

Upgrading the 2017 Infiniti QX30 to LED headlights is straightforward since it uses a single H9 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 H9 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.

How to Replace Bulbs on a 2017 Infiniti QX30

The H9 bulb uses a quarter-turn bayonet mount similar to H11. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. On the 2017 QX30, 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 LED Fog Light fog light socket.

How Long Do 2017 Infiniti QX30 Headlight Bulbs Last?

Standard halogen headlights on the 2017 Infiniti QX30 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 9 years old, the original bulbs on your QX30 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 2017 Infiniti QX30?

The H9 low beam bulb on the 2017 Infiniti QX30 is cross-compatible with H11, H8 bulbs. These share the same physical base and electrical connection, so they will fit the socket. However, H9 is the recommended size because it is optimized for the wattage and beam pattern designed into your headlight housing. 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.

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 H9 LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

A pair of halogen H9 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 H9 LED position are available as direct plug-and-play replacements.
