Horrible first experience but I feel like I worked hard for the end result and for today at least I'm pretty satisfied.
Attempt 1: Going through front bumper via a DIY I found on here which didn't explain what to do after removing the bumper.
After removing it, I didn't see how the headlights were exposed or gave me more room to work with.

So I put the bumper back on, badly scratching up my car in the process.
Attempt 2: Going through wheel well.
More straight forward method. My bulb wouldn't and still hasn't screwed in 100% and I broke one of the prongs on one of the bulbs. However, all is operational and looks good. Couldn't figure out how to connect the harness on one end of the car to the other without it being messy so I'm not using it at the moment.
The well lining is a little out of place but hardly noticeable.
I also installed some LEDs for the stock interior lighting and the license plates.
Looks really good. Tried to keep the 5000k theme all around. However the license plate lights are a little much I think. There's even a glow on the ground from the bulbs.
My dash is very dim when the lows are on. Guess this is because I'm not using the harness' extra battery source?
Learned a lot, took too long, happy with end result.
