Vibe Goggles (Earth-1: Pre-Crisis)

The Vibe Goggles are pairs of goggles created by Cisco Ramon to help him witness his death in an erased timeline.

First goggles
In an erased timeline, Cisco was killed by Eobard Thawne under the disguise of Harrison Wells after the former discovered his true identity. Later in the new timeline, Cisco had visions of his death. Team Flash helped him build the goggles to let him go into his dream and find clues that can defeat Thawne.

Second goggles
After discovering the multiverse, Cisco decided to go to Earth-2 with Barry and Harry in order to find Zoom. However, due to the vibrational frequency of Earth-2 being different from Earth-1, the goggles no longer work. Later, Cisco decided to take his doppelgänger's goggles and used it as a replacement to the Vibe goggles.
