What does the flasher on a 2002 Chevrolet Silverado look like?

The flasher unit on a 2002 Chevrolet Silverado is not something you'd visually identify easily. It's a small, usually black, electronic component, about the size of a dice or slightly larger, and it's not typically visible without disassembling part of the vehicle's electrical system. You won't see it under the hood or in the cabin. It's often tucked away in a fuse box or other electrical junction point, usually somewhere near the steering column or under the dashboard. It doesn't have any distinguishing features visually; it looks like a small electronic relay.
