2006 Dodge truck and a light on the dash that looks like jellyfish came What does it mean?

That's likely the airbag warning light. Many describe the symbol as looking like a stylized person sitting in a seat with a circle around them, which some find resembles a jellyfish.

If this light is illuminated in your 2006 Dodge truck, it means there's a problem with the airbag system. This is a serious safety issue and should be addressed immediately. The problem could be anything from a faulty sensor to a problem with the airbag module itself.

Do not drive the vehicle until the problem is diagnosed and fixed by a qualified mechanic. Driving with a malfunctioning airbag system puts you and your passengers at significantly increased risk in the event of a collision. Have a professional inspect the system to determine the cause of the light and repair it accordingly.
