Lyrics (by way of animelyrics.com):

Kawarunda kawarunda muteki no robo ni
Yuku zo ougon senshi GOLD RAITAN
Ashita ni kaketeyuku oretachi no negai ga
Todoiteiru ka kikoeru ka haruka meka jigen
Omae nara shinjita
Omae nara yareru hazu
Abunagena sekai mamorunda
Kaze wo kitte tobidate Raitan gundan
Tatakau tatakau butai ha oozora da
Seigi wo himete yuuki ni moete
Yuku zo ougon senshi GOLD RAITAN

Kawarunda kawarunda muteki no robo ni
Yuku zo ougon senshi GOLD RAITAN
Ashita ni yume wo miru oretachi no kokoro wo
Fuminijiru no ka yogosu no ka aku no daimaou
Omae dake nikunda
Omae dake aisenai
Ayashigena kage wo tachikiru zo
Kaze wo kitte tobidate Raitan gundan
Tatakau tatakau butai ha oozora da
Heiwa wo yonde mirai ni moete
Yuku zo ougon senshi GOLD RAITAN
