Each 2014 GMC Sierra headlight bulb is installed and aimed to cast light ahead of the truck so the driver can see what' coming up. When one of the headlights isn't working, it can limit your ability to see and react to dangers in your path. Fortunately, fixing up your lighting is usually quick and often requires only a bulb change, and AutoZone has a selection of
2014 GMC Sierra headlights and headlamps to meet your needs.
2014 GMC Sierra Bulb Sizes
Each vehicle has a specific headlight design that requires a certain bulb to fit, casting the right beam pattern and brightness onto the road. Using the wrong type may not fit at all or it could end up damaging your truck' headlamp assembly. 2014 GMC Sierra headlights are all the same, a size 9012 bulb that operates for both high and low beams. If you want brighter lights than the factory halogen bulbs, consider an upgrade to ultra-white or HID bulbs.
Symptoms of Bad Headlights
The easiest symptom to spot a bad headlight is, of course, a bulb that doesn't light up anymore. There could be other signs that headlights need to be changed including dimly lit bulbs, flickering that you notice when driving in the dark, and headlights that intermittently go off when driving over dips and bumps in the road.
How to Replace Headlight Assembly
When you're changing headlights, it' always best to replace them in pairs so they match in color and intensity. The bulbs are fitted into a socket in the back of the headlamp housing under the hood. Gain access to the bulb as required, then remove the dust cover and turn the bulb to remove it. Disconnect the wiring, install the new bulb in its place, and reassemble any parts you needed to remove.
