Just picked up a brand new 2018 TRD Off-road Premium last Tuesday.
Well I guess you could consider weathertech floor mats.
Attempted to install my Xenon Depot H11 HID kit and got nearly done and found out the bulb I was putting in the passenger side was moving around a bit. Come to find out the spot welds on the little tabs had come loose. Could have been like that from the get go or I could have tapped it against something while connecting all the wires and pushing the grommet through the hole I drilled in the dust cover. The driver side was super fast and took probably 5 minutes. The passenger side took forever trying to get into the housing and was just generally a pain in the ass. I’ve already sent Xenon Depot an email and just waiting to hear back from them.
I also installed HID light bulbs on my 2016 4Runner. Very easy installation. HIDs work very well with the existing projector type lens. It has the same sharp beam cutoff as the factory bulbs and the same light distribution. It does not blind the oncoming traffic like the HIDs installed on regular reflector type headlights.
The grommet supplied with HID kit was very weak and thin. I had to put some clear silicone sealant to seal it properly. A step drill bit is a must for drilling holes in the existing low beam light bulb dust covers. If not sealed properly it will allow dirt and moisture into the headlight enclosure.
