Here's how to replace the tail light on a 2011 Toyota Highlander (OEM part# 81550-0E070). When the dealer told me it would cost ~$400 to replace, I started researching to see if I could fix it myself. I didn't find too much info online, so I made this video after I determined I could actually fix it. The best price I could find for a genuine Toyota replacement was ~170 shipped. I opted for an aftermarket Depo 312-19A7R-AF unit purchased from a very large online retailer for $90 shipped.
