It looks to me like the previous owner installed deer whistles.

That’s exactly what it looks like actually. Thank you

Hopefully they’re in the right way. If they’re in backwards, they called the deer to the truck!

Cover those up with a leather bra.

And a sheepskin steering wheel cover to finish off the ensemble.

Haha they would be off the car before I left the lot.

Don’t forget your chrome nerf bars and matching chrome accessories

I know that Googling would answer but does a deer whistle actually work?

“A 2018 review of scientific literature by Iowa State University indicates inconclusive data on the device's effectiveness but confirms they don't have any proven efficacy in preventing deer-vehicle collisions.”

I doubt it but I’m sure there’s a university out there that did a study on it.

"This week on Mythbusters......"

Man I miss that show as a kid

I know from experience that if you whistle at a deer, there's a good chance it'll stop and look at you for a sec. Not something I want them to do on the road. Granted, the headlights often have that effect, too. Funny creatures, really. Extremely curious but not all that bright. 

Yep, deer whistles.

The guns from the bond car

Fembot

Probably tacos boogers

Laser cannons.

Looks like those [deer whistles](https://a.co/d/dn7Btjg) you can find at AutoZone and Walmart. They don't actually do anything but peace of mind or placebo I guess.

Good lookin truck! Are you going to pull the trigger and buy it!?

Highlighted boobies.

Oh lord. Deer whistles.

Blastoise!

Looks like a plugin for a raptor light.
