What are these bumps on my headlights?

[PickupMan]

They are situated right over the turn signal, and have some grooves on them. No idea what they are.

A light diffuser so it spreads the light to the sides. Part of the engineering that went into the turn signal portion of the light. It was probably lower cost to put it on the outside then have it internal.

Yeah, that's what its for. Am I the only one that has a hard time seeing turn signals from the side on newer vehicles? The old ones had a side lamp that is actually visible. I find myself yelling at drivers for turning with no signal on, and once they start going around, then I can can see the blinker. I think these suck.

 

Yeah, I know, get off my lawn. haha.

No, you're not. For the life of me, I cannot understand why GM did not put side turn signal indicators on the mirrors of these trucks.

I would just continue with this method, you will have a 50/50 chance of being correct every time
