replacement front turn signal bulb?

Today, my Tundra front turn signal bulb stopped working. First problem i have had with the truck since bought new. Can someone please let me know the bulb part number and instructions for replacement? Quick search i found nothing. It is all stock. Thanks in advance.

 

From my 2016 Manual. If memory serves me….the bulb is accessed easily at the back of the headlight assembly under the hood. Just twists out?

 

Thanks. So i still need more help. I went to get replacement bulbs and O'Reileys only had 3157 and it showed direct replacement on their computer and he says if it doesnt work brink it back. So i install it and drive away and two minutes later the turn signal is not working again so i head to another auto parts store and get the 4157 and put it in and it works. Then two minutes later its not working again then i got home and its working again. I see no evidence of any rodent chewing damage on any wiring so whats going on here? The bulb is inserted all the way.

 

The front turn signal/DRL to my 2014 was 3157CK..

Does your 2016 Limited have amber DRLs or the white LED strip on the bottom of the headlight?
I don't remember when the white LED strips came out.

Is it right or right or left and right turn signals?

Also, is the rear turn signal working?

 

Its SR5

 

I feel dumb. LOL I didnt have it pushed in all the way like i thought i did.
