Turn signal bulb size?

Can someone tell me the bulb size I need for the parking light/turnsignal on my 2018 Tundra? I just keep finding aftermarket parts numbers and figured it would be quicker to ask here.

Thanks guys!

 

4157 front 921 rear

 

Thank youuuuuu!!

 

Wrong. 7443 front.

 

7443? For a 2018 with Halogen headlights?

 

Owners manual???

If I were home right now I would check the owners manual...I'm trying to order some right this minute. I though I would ask on here while I'm at work and get some helpful replies, not snarky responses.

 

You didn’t specify originally. In that case it’s 3157

 

Sorry, I forgot that some came with the LEDs that year. I appreciate it!

 

If you have halogen lights then it's 3157/4157. OEM LED headlights are 7443. You didn't specify in your OP so there is some speculation going on.

Was thinking of doing lol
Not snarky, just an simple answer

 

Sorry, I'm just having some problems with my Tacoma and that's already got me annoyed. I didn't mean to grump at you guys.

 

You're good. Most of us on here are just bored during the day and like to engage in mild trolling is all.

 

We all trying to help you, use the link I sent

 

Thanks. I'm sorry I was grumpy

 

All good

 

Okay, last question...are the 3157/4157 and 3157NA/4157NA the same thing? And do I need the amber or clear ones?

 

2018 Tundra Owner Manual: https://www.toyota.com/t3Portal/document/om-s/OM0C009U/pdf/OM0C009U.pdf

See Page 609.

*3: LED headlights = 7444NA front turn signal (The "A" in NA is for amber)
*2: Halogen headlights = 4157NAK front turn signal and parking lights (The "A" in NAK is for amber)

 

Vleds shows 3157CK for halogen on the 2018.

 

Both bulbs have the same wedge base and are interchangeable. But, 4157 is filled with krypton gas and has 4X the life of 3157.

The "NA" in 4157NAK is for "natural amber" meaning the bulb glass itself is amber, not tinted, and the "K" is for "krypton".

 

Man, you guys are awesome! Thank you! I just got home from work, so you all saved me a bunch of time trying to figure it out. Also, I just realized my used Tundra didn’t come with a manual lol. I just recently bought it, last month. I’m going to order a manual very soon.

 

Toyota gives the PDF version for free which is cool

 

AWESOME!! Thanks!
