Let there be LED light...
I kind of spoiled myself with my last few cars by putting LEDs in them. The white light looks so nice whether its coming from headlights, map lights, puddle lights, reverse lights, license plate lights, etc. When it comes to the interior bulbs, I went straight to amazon as I have used them many time before with great luck. You will need two packs of these:
https://www.amazon.com/gp/product/B06VVWTPT1/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 and a pack of these:
https://www.amazon.com/gp/product/B00ZKTXJA4/ref=oh_aui_detailpage_o05_s03?ie=UTF8&psc=1 to replace all interior lights, courtesy lights, license plate lights and (factory) reverse lights. All extremely quick and easy to install. Inexpensive mod that gives your runner a great look.
I also went ahead and did the tail-to-turn mod by Diode Dynamics while I was at it:
https://www.diodedynamics.com/2014-2017-toyota-4runner-tail-as-turntm-module-backup-module.html. This is a pretty cool kit because it bypasses the ugly amber turn signals in the rear and uses the factory LED brake lights as the turn signals as well. You can also opt to hook up one more wire and it turns the old turn signal outlets in to reverse light outlets that can be supplied with bigger and brighter white LEDs so people REALLY know when you are backing up. The Diode Dynamics kit has great video tutorials online and is very easy to install. I think it took me about 15 minutes for both tail lights. I used these bulbs to replace the old turn signals, which are now reverse lights:
https://www.amazon.com/gp/product/B07414XVKT/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1. The output on these is AMAZING!
When it came to the headlights and fogs, I did a LOT of reading and researching and went back and forth many times before pulling the trigger on a set. I was sold on the XenonDepot kits until I came across a particular thread on here (I wish I knew the guy's name so I could give him credit) referencing some LEDs off of amazon. I figured being a prime member and having the simplicity of hassle-free returns, why not give it a shot at least? So, I went ahead and purchased these for the lows and fogs:
https://www.amazon.com/gp/product/B01MXMIRY6/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1 as well as these for the highs:
https://www.amazon.com/gp/product/B06XBD2Z8V/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1. The lows and fogs went in VERY securely with little to no play in them. After testing them at night, I was pleasantly surprised with the output and decided to keep them in. The color is great, the pattern is perfect, and they throw a great amount of light to be able to see whats in front of you. The highs on the other hand, did not fit well in to their socket and they had some play in them so they went back to amazon. When I returned them, I came across these:
https://www.amazon.com/Cougar-Motor...pID=51eyTXd5FvL&preST=_SY300_QL70_&dpSrc=srch, which had great reviews so I thought what the heck and ordered them. These lights are freaking awesome. They are SUPER bright and I have no issues seeing way ahead of me when the high beams are on.
A little side note...I did the DRL mod mentioned in this forum, which completely deactivates the DRLs from running. I don't like the way they look and I didn't want to have any voltage/flickering issues with the LEDs. I run my headlights at all times to maintain visibility on the roads.
I will be posting some photos of all of the lights, but unfortunately proper lighting colors are just hard to capture on a camera. Though it may be hard to tell, all of the lighting is super bright and a nice, crisp white color. Looks very clean.

Sooo...I went with the n-fab steps as I personally love the way they look. Find them here:
