What Lighting System Does the 2016 Lexus NX300h Have?
The 2016 Lexus NX300h features an extensive lighting system with 11 bulb positions. It uses factory LED technology with integrated LED headlight modules. The NX300h has been available from 2015 to 2019, and the 2016 model falls in the early-generation years.
Can You Put LED Bulbs in a 2016 Lexus NX300h?
To upgrade the 2016 Lexus NX300h headlights to LED, you will need a LED Headlights LED kit for the low beams and a 9005 LED LED kit for the high beams. Start with the low beams since they are used most often and have the biggest impact on nighttime visibility. 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 2016 Lexus NX300h
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 2016 NX300h, 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. This vehicle has factory-integrated LED headlight modules. These are not user-serviceable bulbs. If your LED headlights fail, the entire headlight assembly or LED module may need to be replaced by a dealer or qualified technician. 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.

Shop Complete LED Kit for 2016 Lexus NX300hHow Long Do 2016 Lexus NX300h Headlight Bulbs Last?
Factory LED headlights on the 2016 Lexus NX300h are rated for approximately 25,000 to 50,000 hours of use, which translates to roughly 10 to 15 years of normal driving. LED modules rarely burn out suddenly. Instead, they gradually dim over time or develop dead zones within the LED array. At 10 years old, the original bulbs on your NX300h are likely overdue for replacement, though LED modules may still have life left. 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 2016 Lexus NX300h?
For the high beams, the 9005 is interchangeable with HB3. 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.
