I have been a lighting geek when it comes to my vehicles for 35 years. If it was replaceable/upgradeable I did so. Sometimes at great expense. Upgraded halogens, HIDs, projectors, LEDs- tried them all. All have their weaknesses and strengths relative to price points and ease of install or adaptation.
I did some digging online before pulling the trigger on the Land Cruiser knowing they wouldn’t be readily upgradeable, and I am pleasantly happy with it as it came right off the showroom floor. Yes there are “V” patterns visible when driving at night (for reasons mentioned in this and other threads) , but Toyota did an excellent job on their LED headlights, at least in the Premium trim. Overall brightness is good at distance, as well as up close, with good coverage curb to curb or shoulder to shoulder. I have yet to meet another Land Cruiser approaching at night, so I can’t comment on how easy these will be on the eyes of oncoming traffic.
For owners who drive areas where they are likely to run into wildlife or rockslides in the roads, these are going to perform pretty well. I don’t see the aftermarket flooding the market with upgrades for the Land Cruiser headlights any time soon.
