Okay so, I drive a 2007 Trailblazer LS & my bulb for my check engine light seems to be out but my engine light itself is on but I’m just unable to see it meaning it’s been on for idk how long and I’ve assumed that it wasn’t because of course my bulb is out so it doesn’t light up, does anyone know where I can find any replacement bulbs? I’ve looked everywhere it seems, and I can’t find any. I need it so I know when it’s on or if it goes off and I also need to pass emissions. Any help is appreciated! Also any videos that show how to replace it would help as well. Thank you.
