2015 king ranch. My passenger side running light bulb went out (but the turn signal still works) along with my driver side running light on my mirror. Both light bulbs went out at the same time. Seems pretty strange.

How hard are these to replace?

 

The front marker lights are a bear. Only way I found to do it is remove the grill and the headlight assembly. The mirror lights are really easy... crank the mirror all the way to the side opposite the lights and you'll see the clips that hold them in.

 

Yes, you need to use a screwdriver and work the clip behind the mirror glass topop the lenses out. One of those things we hate todo because it's plastic and easily broken.

I swapped every bulb in my truck over to led. I've already got a parking light out in my mirror which frustrates me. The led bulbs are nice and bright though and I run my lights on anytime I'm driving.
