This page for the 2015 Infiniti Q50 helps you verify bulb sizes by lighting position, so you can match the correct replacement to the exact lamp on the car. Whether you are changing a headlight, tail light, interior bulb, or license plate light, checking the bulb chart by location is the easiest way to avoid buying the wrong part.
The 2015 Infiniti Q50 uses different bulb types depending on the light position, and some applications may vary by trim, market, or body style. Use this guide to compare the front, rear, and interior lighting points before ordering, especially if your car has factory LED lighting or a lighting package that changes the original setup.
Fitment on the 2015 Infiniti Q50 can vary between trims and regions, so it is smart to confirm what is actually installed on your vehicle before purchasing. Some positions may use LED assemblies from the factory, while others may still use replaceable bulbs, and aftermarket conversions can change the required size or connector style. If you are upgrading from halogen to LED, check for bulb depth, polarity, heat sink clearance, and any warning messages or flicker issues. For the best match, compare the old bulb to the replacement and verify the socket before you buy.
The chart shows LED for both the low beam and high beam headlight positions on the 2015 Infiniti Q50. Because the exact setup can vary by trim and market, confirm the installed headlamp assembly before replacing any part.
Yes, the fog light bulb position is listed as LED. If your Q50 is equipped with factory LED fog lights, you may need to replace the entire LED unit rather than a simple replaceable bulb.
The rear turn signal light bulb is listed as 7440A for the 2015 Infiniti Q50. Always check the socket and lens type before ordering, since some lighting packages can differ.
The license plate light bulb is listed as 168, 917. These are common wedge-style bulbs used in many interior and exterior small lamp positions.
The dome light bulb is listed as 194, 7441. If your vehicle has an upgraded interior lighting package, verify the bulb shape and base before replacing it.
For the 2015 Infiniti Q50, the map light bulb is listed as LED, while the interior door light bulb is listed as 168, 917. That means the two locations do not use the same bulb type.
The brake light bulb is listed as LED. On LED-equipped rear lamps, the light source may be built into the assembly, so replacement can be different from a standard halogen bulb swap.
Yes, many owners use aftermarket LED replacements, but fitment depends on the socket, space behind the lamp, and vehicle electronics. Check for proper beam pattern, polarity, and any hyperflash or bulb-out warnings if you are changing turn signals.
The safest method is to inspect the installed bulb or lamp assembly and compare it with the bulb chart for the exact lighting position. This is especially important on the 2015 Infiniti Q50 because trim and lighting package differences can affect fitment.
Not always. Trim level, body style, market, and optional lighting equipment can change the bulb setup. Use the page as a position-by-position guide rather than assuming every Q50 uses the same parts.
The back up reverse light bulb is listed as LED. If your reverse lamps are factory LED, replacement may involve the lamp module rather than a standard bulb.
The trunk or cargo area light is listed as 158. This is a useful reference when replacing the cargo lamp or checking an interior convenience light that has gone dim or failed.
