2012–2016 Hyundai Elantra Headlight and Bulb Sizes

Which Hyundai Elantra model years does this cover?

These headlight bulbs specifications apply to every Hyundai Elantra built from 2012 through 2016 — the MD/UD (5th generation), compact sedan (also sold as coupe 2013–2014 and gt 5-door hatchback through 2016 on the related ud platform). 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 2012–2016 Hyundai Elantra

• 2012MD generation launch (sedan only)

What headlight bulb does a 2012–2016 Hyundai Elantra use?

H7 (halogen; projector on some Limited trims) for the low beam and H1 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 2012–2016 Hyundai Elantra take?

H8 (where equipped).

Can you put LED bulbs in a 2012–2016 Hyundai Elantra?

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.
