Traffic Signal - Green
Target a monster on the turn player's field; this turn it can attack directly, but other monsters can't attack, also if it is in Defense Position change it to face-up Attack position, also you may set a "Traffic Signal - Yellow" from your Deck. You can banish this card and 2 other Normal Trap cards from your GY; Special Summon a Machine monster from your Deck.

Traffic Signal - Red

Perhaps your Traps should have "You can banish 3 Normal Trap Card with different names from your GY, including this card;" as otherwise it can be a bit too easy to activate for free monsters from the Deck. Green nets you a Kozmo or again any Machine monster your Deck needs. World Legacy also comes to mind. But by upping the requirement, I think it will be limited in a good way. 

On the other hand, adding a restriction like that really does hurt these card's playability, as you have to wait 3 turns to use it within the set, which is really one of the most efficient ways to use it in the first place. Yellow and Red are definitely the best 2 of the Deck, with Yellow being really useful for locking out your opponent's plays for a turn and hitting Extra Links, and Red being an almost better Breakthrough Skill. They seem better at being generic than part of this laddering set. Hm.
