Hey Texas, my wife has a Highlander with the lights you have. I just purchased a new Ford Edge with standard LEDs. Verdict from both of us: night and day difference goes to LED. Remember the old adage....”ignorance is bliss”. By not using LEDs , Toyota probably saved $10 a car, times about 244,511 HL sold in 2018 amounts to $2,445,110 in their pockets. Toyota because of its reputation for reliability can afford to delay technology a few years.Call us old and unaware (recently retired) if you want but I was surprised to see all the complaints here about the OEM headlights after buying our 2017 HIHy Limited Platinum. I asked my wife, who shares the HiHy driving with me around town and on trips we’ve taken if she ever felt the lights are inadequate and the response was the same as mine. They seem fine to us! What are we missing?
BTW, if you are recently retired, I’m about 10 years ahead of you. My grand children keep me up to date, or try to.
