Help!!!

We're having a family crisis here and we need help. Can anyone remember a kids TV series about a group of teenagers who wore one piece costumes, wore helmest and always defeated their criminal opponents by using judo. Each one had a different coloured helmet and suits.And no, it wasn't Teenage Mutant Nina Turtles. If no one can answer this the BillB household may descend into chaos.
Please help, if you can.

You got it, Anna. Mighty Morphin Power Rangers. Peace has once more descended on our home. Thanks a lot.
