That’s not a light
This person took a picture of his engine that is clearly on fire and asked the internet for advice. His question was ‘does anyone know what it means when this light comes on?’. Well, we definitely don’t, but what we do know is that you need a fire extinguisher as soon as possible to deal with that problem.
How did this person’s engine catch fire and why did he just watch it burn, take a photo and post it online instead of running away or doing something? So many questions that we will probably never get the answers to. But if they are still out there looking for answers, we would suggest putting the fire out first.
