2021 AT4... which bulbs are halogen still?

[RCF71]

I tried searching, but couldn’t find an answer...

 

I know my license plate light are halogen, and gonna order some LED replacements from Diode Dynamics.  Was hoping to identify any others and get replacements for all of ‘em at once.

 

Thanks in advance for any help!

So be careful. A few of GM’s see an led bulb as an open circuit. You would think by now they would figure that out.

Yep, understood.  Diode Dynamics will usually mention and offer a resistor if this is the case - had to add one to my reverse lights on my Camaro when I swapped ‘em out.

I have the same truck and same year......the only bulbs halogen are the 2 license plate bulbs, which I dont understand why GM couldn't make those LED like everything else. 

 

The Lasfit brand license plate bulbs are the ones to get in my opinion,  they say on there website it wont throw a code. Have had mine in 2 months and no code issues.

Thanks for confirming and the recommendation!  
 

I ordered the Diode Dynamics bulbs (lowest lumens in clean white) - have them in my Camaro and in my F150 that this truck replaced - no issues with about a dozen different replacements!  Will post pics once installed.
