Ask HN: What are the best programmable holiday lights?
https://kno.wled.ge/
Many 'effects' already prepackaged. Plus the ability to schedule time based changes (on/off/change pattern/etc.). Includes a web server to provide "app like" control over a phone or PC. Also includes integrations for several "home control" systems and a http API for programmatic control from another system. Can even synchronize plural controllers into a whole 'net' (note, I've not used this feature yet).
Small ESP32 boards (with wifi capability) such as this example (no affiliation, just an example that works):
https://www.amazon.com/dp/B09Y8X1GK7
WS2811 LED strings [1] (of which there are an infinite variety) suitable for outdoor use. One example (no affiliation):
https://www.amazon.com/dp/B0CYZF1WCR
Suitable power supplies, outdoor weather sealed boxes, and wiring (all left to you to locate).
Willingness to assemble the pieces and some time to do so. Having a soldering iron is helpful here, although one could possibly get by with screw terminal blocks inside weatherproof boxes if need be for many of the 'connections'.
[1] Or other 'programmable LED' strings for which WLED is compatible (it works with numerous different programmable LED standards, browse the WLED website for details).

Anyone know where I could obtain these
I’ll do you one better: Here is the WLED main site - they cover everything - however you want it for your vehicle is up to you! (If you want to see a truck I personally worked (with 2 other main guys doing the woodwork and wiring) on that was probably the “most expensive” project with these controllers, check out the SEMA entered “Realtree Stormtrooper truck” - a LOT of time went in to that and almost a year of prep, not a fan myself, but custom electronics are what I like doing)

The perfect WLED board... is not working.
Did you use the esp32.bin? If so, you should instead use ESP32-C3 here: https://github.com/Aircoookie/WLED/releases/download/v0.14.0/WLED_0.14.0_ESP32-C3.bin

How do I get LED strips here? My plan is to use Govee H619A and PVC U profiles again (like in the last pic) for the green part but how do i get electricity up there? the outlet is X'ed 'cause theres gonna be a shower right under it and theres only one more outlet next to the sink in pic 2
Friend replaced all his govee cintrollers with WLED.

Multiple RGB outputs
Sweet. Then pretty much any arduino or other microcontroller would take care of what you need. The strips only take one output pin plus power and ground so just about everything will work for driving them. They act like a long shift register so the single pin is all that's needed to load the full strip with whatever patterns you want regardless of the length. You just have to tell it how many LEDs there are in total is all. Check out the FastLED library. You can learn more about it there and/or install the library in the IDE by pressing "ctrl shift I" for windows or "command shift I" for mac and search for it in the upper search area and install it right there. It comes with working examples too so all you would have to do is install the library, load one of the new example sketches that came with it, and probably edit the example to change the NUM_LEDS count to match what you're working with.
