How to change 2014 Dodge Ram sport turn signal

unless there’s an access point in the back to reach them then yes either the whole assembly or a DIY job. if you haven’t done it before the headlamp will need taking out which can sometimes mean removing the bumper which can be a right pain (try find a YouTube video on how to remove them) and will either be held together by small screws holding the lens and back cover together which is nice and easy or glued all the way around. if its glue you’ll need a heat gun to melt the glue and open it up but it can get messy and ruin the casing. obviously if you can find the correct size bulb as well.  before you do any of this though try and access them from the cap on the back to change the dipped beam and side lights.
