A difference between Pokémon: Let’s Go, Pikachu/Eevee, and other Pokémon games is the change from Hidden Machines or HMs to Secret Techniques. Your partner Pikachu or Eevee, depending on which version you own, can learn these Secret Techniques outside of battle to help you clear obstacles and travel throughout the Kanto region. So, basically the HMs in the previous Pokémon games. In this guide, you will learn how to obtain the Light Up Secret Technique.

Pokémon Let’s Go Pikachu/Eevee: How to Obtain Light Up Secret Technique (Flash)

The Light Up Secret Technique allows your Pikachu or Eevee to literally light up the dark caves so that they are clear to see. With this Secret Technique at your disposal, you and your Pokémon partner are able to traverse through and explore dark caves that you initially could not explore.

The Light Up Secret Technique is this game’s equivalent of HM Flash. Every HM from the previous Pokémon games has been changed: Cut has been changed to the Chop Down Secret Technique, Surf has been changed to the Sea Skim Secret Technique, Fly to Sky Dash Secret Technique, and, finally, Strength to Strong Push Secret Technique.

Light It Up, Pikachu/Eevee!

  1. From Vermillion City, head east to Route 11, and enter Diglett’s Cave.
