The 2009–2012 Toyota Highlander uses halogen Tail lights that vary by model year and trim, with a notable difference in the bulb type and housing design. Early models (2009–2010) typically feature a reflector housing using a single H4/9003 bulb for both low and high beams, while later models (2011–2012) often use a projector housing with separate H11 (low beam) and 9005 (high beam) bulbs.
