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.htmlDoes 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.
