What Lighting System Does the 2019 Fiat 500 Have?
The 2019 Fiat 500 features an extensive lighting system with 12 bulb positions. It uses halogen technology with a single 9012 LED dual-filament bulb handling both low and high beams. The 500 has been available from 2012 to 2019, and the 2019 model falls in the late-generation years.
Can You Put LED Bulbs in a 2019 Fiat 500?
Upgrading the 2019 Fiat 500 to LED headlights is straightforward since it uses a single 9012 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 9012 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a H11 LED LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2019 Fiat 500
The 9012 bulb uses a quarter-turn bayonet mount similar to H11 but with a unique tab. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. On the 2019 500, 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 H11 LED fog light socket.

Standard halogen headlights on the 2019 Fiat 500 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 500 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 Fiat 500?
The 9012 low beam bulb on the 2019 Fiat 500 is cross-compatible with HIR2 bulbs. These share the same physical base and electrical connection, so they will fit the socket. However, 9012 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.
