MPC 1978 Dodge D100 Part Question

[Jim B]

I am beginning to build the MPC 1978 Dodge D100 pickup kit, and I have a part I cannot identify.  It's Part Number 112.  I've found them on the chrome tree, and I still have no idea what they are.  Are they some sort of turn signal or something?

Probably some sort of extra part from past versions.  I can’t check mine (packed away).  Can you post a photo?

Here you go:

It's "optional", so I'm not terribly worried about it.

Auxiliary signal?

[Jim B]

That's what I'm thinking. 

[Rob Hall]

Yeah, extra lights..can see it on the 1974 box art...

Could also be fender mount mirrors.
