Ford Mustang
Headlight Bulbs Replacement Guide
How to change the low/high beam and turn
signal bulbs in the headlights of a revised 5th generation 2010-2014 Mustang.
 2012 Mustang Headlight |
 Dual Low & High Beam |
 Look Behind Housing |
| This
automotive maintenance tutorial was specifically written to assist
owners of the updated fifth generation (2010, 2011, 2012, 2013 &
2014) Ford Mustang in changing a burnt out combination low & high
beam bulb or the front turn signal light bulb in the headlight
housings. Owners of the earlier 5th generation Mustang from 2005 to 2009 and possibly the 4th generation 1994 to 2004 models with similar headlight assemblies may also find these DIY instructions to be helpful. Replacement bulbs for the 2010 to 2012 Mustang with their part numbers are as follows: Dual Beam Headlight # H13 and Front Turn Signal # 3457. The 2013 (and perhaps also the 2014 models) use a D3S HID (high intensity discharge) headlight bulb and a 7444NA turn signal bulb. No tools are needed to change any of the headlight bulbs. |
