Hi, I am a novice when it comes to electricity, so slam me if this is wrong. I want to hook up some interior LED strips to my car. I've attached a schematic above, but I'll give the rundown:

• Two 5V SK6812 60LED/m strips

• Cigarette lighter 12V (15A fuse, can get 20A if necessary)

• 12V->5V 20A buck converter (more amps at lower voltage)

• ESP32-WROOM-32E with WLED flashed

• Small enclosure to keep everything nice and tucked away

Why did I choose cigarette lighter instead of fuse tap? I don't want to drill holes in my fuse box and I don't want to tap into factory fuses.

According to the manufacturer, the SK6812 uses 0.06A per pixel. I have ~300 pixels, which comes out to 18A max. I know this includes all RGB channels and the W channel, which is unrealistic, but I want to prepare for the max and ensure it's safe no matter what. Plus, I might crank the baby up.

The reason I'm using 5V SK6812 instead of 12V is because I want each LED to be individually addressable. The reason I'm not using a strip like WS2811 or WS2815 is because the power usage is significantly higher and it doesn't have a dedicated white channel.

Overall, this is my first time doing something like this and I just want to confirm my car won't blow up. I have experience soldering, so that shouldn't be a problem. Any suggestions on where I can improve, what can go wrong, better methods, better parts?

I'll leave a list below of the parts I plan to buy:

• Buck Converter ($4.82)

• 12AWG Wire ($3.89 1M)

• 18AWG Wire ($9.38 5M)

• Cable Sleeve ($3.37 10M)

• Fake Wago-Connectors ($4.5 5pc 3-3-port, 1pc 1-4-port)

• Cigarette Lighter ($2.91)

• ESP32-WROOM-32E ($4.59)

• SK6812 ($24.97)

• LED Strip Diffuser ($17.03)

• Enclosure ($7.66)

• Heatshrink ($2.11)

I really want to install ambient lighting to my 2013 Acura ILX and get it to look somewhat like this: https://www.flickr.com/photos/theacphotography/16033940826/in/photostream/

or at least this: http://www.9thgencivic.com/forum/attachments/lighting/9169d1342659619-diy-better-interior-ambient-lighting-imageuploadedbyautoguide1342659615.906906.jpg

Most of the kits I've been finding come with 4 strips, which would work great if I only wanted to illuminate the footwells or the underseat area. But I also want to put lighting in more visible areas like under the hood of the dashboard, in the cupholders, and maybe some on the doors, but I don't know how to do that without having there be an ugly visible LED strip.

I'm totally confused as to what kind of products I should get for this type of setup and I'm not even sure if it's possible unless it's factory made. Whatever I get, I plan on installing it myself to get the positioning right, and then taking it to a mechanic so that the wiring won't be visible.

If anybody can help me with out with what kind of kits/products I should buy, I would really appreciate it. I'm looking for pink lighting primarily, but would prefer to be able to change the color. Also, I don't care if the lights flash or pulse along with music, but it would be a bonus if that setting was available.

Thanks in advance!
