What's this???

2000 ac. We got home after dark a couple nights ago and noticed a faint flashing under the driver's side dash. Investigation revealed a small, round, green bulb above the parking brake flashing. It's the first time we've noticed it in 2 years of ownership so we suspect it just started out of the blue. Can anyone identify it? Thanks guys, Marty

 

Got a picture of it?

 

That sounds interesting. Never heard of that. Maybe something aftermarket?

 

It’s just a regular cab light that turns on when the doors are open. Its probably not pushed in all the way. It’s a T5 bulb.

I replaced mine about 2 months ago.

 

Its the tracking device. Pretend that you haven't noticed it!

 

My tundras flashing light is blue. Part of security system. One of those things you don’t really notice.

 

I installed high quality foil in my headliner to block the signal years ago. Only rookies haven't done that mod.

 

You’d think by now they’d put tracking devices IN the tin foil!!!!

 

I had a woman come in to the dealer today for us to inspect her vehicle for a tracking device…

 

I would’ve taken her phone and handed it back to her, and said “found it.” Lol

 

Thanks guys, I guess the real question is who's tracking me and why? Do you know where I am right now? I'm going to hold off on the tin foil mod for now for fear that my own thoughts will bounce off of it and come back to me. Thanks for all the replies.

 

Confucius says, Mexico but previously Colorado !

Have you checked what @jerryallday mentioned ?
Care to show pic of this mystery light ?

Aliens.

 

Blinker fluid low warning light

 

Maybe it's a light to illuminate the footwell?

 

This is what mine looks like.

 

That's gotta be a bummer when using the parking brake. Definitely wasn't thought out when the installer was picking a location.

 

Never been an issue

 

I had a lady make us pull out all her plugs and switches to check for "devices". Crazy people man.

 

Sadly, it's more prevalent than ever thanks to social media and/or the internet, depending how you look at it. I need to open a tinfoil hat store, I'll make a killing!

 

Probably also depends where they bought there car as to whether or not it has an immobilized on it. Used to deliver them to the buy here/pay here dealers.

 

This is ours after 18 years and size 13 feet.

 

Honestly, nothing a little Simple Green on a towel probably wouldn't get rid of STAT

 

Should have take a closer shot of the black box that has been knocked off its perch

Father-in-law had some pretty greasy shoes from working the grill for over 30 years.

 

On a serious note though...what the heck is it? There is a red LED facing front and a push button on the back. We don't have the owner's manual or key fobs. Wife's father doesn't seem to recall.
I have the confused...

 

Most likely security related, possible aftermarket alarm installed. I’d follow the wiring to see where it leads to.

 

Start where all investigations start. Where do the wires lead you?

Maybe is brake controller cabling? Something related to security? I don't think it's OEM. Is FIL the 1st owner?

 

FIL is the original owner. Box is in the same spot as the original poster's (see below). I think it is disabled as it doesn't illuminate and pushing the button on the back doesn't prevent the truck from starting.
