Does no one know the bulb part numbers? Nothing in the manual and I cannot find any information on auto parts stores. I even called like 3 dealerships and they all tell me if there is a bulb burnt out bring the car in and they will change it (for a fee of course).

I do not have any bulbs out but would like to know what the common bulbs are so I have them at the ready if I need to go get a replacement.

This might help you out @bobiroc, hopefully it's the right match because I haven't been able to find anything else. https://www.partsgeek.com/catalog/2019/chevrolet/blazer/body_electrical/headlight_bulb.html

Thank you. I don't know why they did not list common bulb replacements in the manual. My last cars had that in the manual. Maybe it is a ploy to get people into the dealership so they can charge an arm and a leg just to change a bulb.

Now I am curious if I were to replace the incandescent bulbs like in the brake lights and turn signal lights with LED versions will I get that fast blink issue. I am not sure why Chevy went with incandescent bulbs anyway. Especially in the higher end trim versions of the Blazer.

No problem at all, glad to help. It probably is their plan to get people coming back to the dealership for servicing. Using incandescent bulbs was a short sighted move by Chevy.
