2012–2013 Toyota Highlander Headlight and Bulb Sizes

Which Toyota Highlander model years does this cover?

These headlight bulbs specifications apply to every Toyota Highlander built from 2012 through 2013 — the XU40 (2nd generation, final years), mid-size 3-row crossover suv. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What changed during the 2012–2013 Toyota Highlander

• 2012Carryover of the 2011 facelift (revised fascia, PSX26W fog lamps). Towing: 5,000 lbs V6 with factory tow prep (3,500 without), 1,500 lbs 2.7L, 3,500 lbs hybrid
• 2013Final XU40 year; subject of the 14V-148 second-row seat recall

What headlight bulb does a 2012–2013 Toyota Highlander use?

H11 (halogen) for the low beam and 9005 (HB3) for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

What fog light bulb does a 2012–2013 Toyota Highlander take?

PSX26W (where equipped).

Can you put LED bulbs in a 2012–2013 Toyota Highlander?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
