As a popular choice for upgrading headlights, understanding the installation steps of led bulbs is helpful to upgrade your vehicle's lighting system correctly and quickly, and enjoy better safety and wonderful driving experience! Today, we have selected AUXITO Q16-H11 LED Bulbs as our installation target to explain, and before we explain the installation steps in detail, we can watch the installation video and understand the characteristics of the Q16 series product specifications.
SPECS

AUXITO Q16 series LED bulbs adopt 1:1 beam pattern technology and 0.039-inch ultra-thin substrate, which concentrates the beam on a farther road without dazzling oncoming vehicles and has a clear cut-off line. And there is a turbo active fan at the bottom of the bulb, which keeps the light cool and prevents overheating, so that the LED bulb lasts longer. Besides, the AUXITO Q16-H11 LED bulbs adopt a plug-in wireless design, which can be completed simply by plugging it in. Below are its specifications.
One thing to note is the Auxito Q16-H11 bulb has a large bottom fan design, so there will be a small chance that the dust cover you would have used will not fit. If you don't want to replace the original dust cover or won't accept installing a bulb without one, we recommend the M3 series to address these concerns. This series has a more compact design, almost 1:1 the size of a halogen lamp.
Overall, Q16-H11 LED bulbs are compatible with 99% of vehicle systems, which can be used as a priority for upgrading headlights.
Now, let's start today's AUXITO Q16-H11 LED Bulbs installation tutorial.
Before installing the bulb, you can do the following preparations.

After doing the above preparations, we started the three-step installation.
Open the hood of the car, find the location of the replaced bulb and peel off the round dust cover (if you have).

Then by rotating counter clockwise to loosen it and remove the old bulb.

Finally Unplug wire harness.

First connect the LED bulb to the plug, during this process, you will hear a "click" to indicate successful insertion.

Then find the correct correspondence and align the dimples on the insertion port before inserting.

While pressing down the led bulb, turn it clockwise until it locks in place.

Finally, install the LED bulb chip at 9 o'clock and 3 o'clock to ensure the correct beam pattern is displayed.
