2021 Suburban RST Back Up Light Bulbs, Rear Turn Signal Bulbs and Rear Brake Bulbs

[mgarrard]

We just purchased a new 2021 Suburban RST. Love the new Burb! But, we don't love the cheesy light bulbs they put for the back up lights, turn signal lights and rear brake lights. We want to replace these bulbs with LED bulbs but can't find any! All I see are people having problems with LED bulbs and getting error messages on the dash. Has anyone changed these bulbs to LED bulbs with success?

Hey, 

 

I have a 2021 Tahoe RST - same situation. 

 

I bought these from amazon for the blinkers - worked fine, no issues.

I bought these reverse lights, and had to add load resistors in order to get rid of the error messages. So far so good. But they are not can bus error free as advertised.

They claimed to be can bus error free but they lied, or at least they weren't for my Tahoe. I didn't bother with the brake lights because honestly they were behind the red plastic its not that obvious. The blinkers and reverse lights are a substantial improvement in light output over stock, especially at night. 

 

Hope this helps,
