Please explain what I think these are.

Ok so Im a bit confused on my flasher situation. I have 3 things that look like flashers to me. 1 is tucked up by the fuse box on the drivers side and is identical to the one that is mounted in a clip next to the ash tray. I believe both of these are flashers correct? Sorry its fuzzy but its says Little Fuse with DOT in a square box and they are identical.

Then I have a much smaller one that is tucked up under the dash between the steering column and ash tray. What is this little one?
