Hi everyone, can someone please show me how to replace the license plate light on 2018 Murano Platinum? Thank you!

Hi and welcome to NICO Club!

For those lights, you can use the Factory Service Manual for specific instruction (though a bit complicated in delivery). I like the FSM myself, combined with some video or photo write ups. I did not find a good photo write up. Also, the FSM is for an older, similar model. I don't find the latest available just yet. Congrats your your new ride!
Here's a link to all chapters: http://www.nicoclub.com/FSM/Murano/2016%20Murano/
...and just the exterior lighting chapter with your license plate lights explained in there:

Here's a tube video I found showing less detail, but the overall gist is in there.

PS - your car is so new, I'm surprised a bulb is out. I know you could get a replacement and take it to the dealership. It's so new, they'll probably show you how to change it at the same time as doing it for you. Just an idea.

I just want to replace it with a white bulb thank you for your reply.

Okay. Hopefully the instructions to access the bulb will work for you. Let us know if you have a specific question about that process. Do you need a bulb size?

I got it replaced, i had to take off the back panel on the lift gate, can't believe it's that complicated to replace that bulb LOL Thank you.

Shoot, I've seen some headlights where you have to take apart the whole bumper to change them! Not quite like the good ol' days. I'm glad you got it done. Did you have to replace any fasteners or where they all reusable?
