Yellow/greenish LEDs

I saw 2 motorcycles from a ways a way with nice bright yellow almost greenish lights on them. When they passed by my i could see they were LEDs. These lights were very noticeable from a distance and i would really like to get some for my bike as day time lights so i can be noticed much easier by other drivers. I haven't been able to find any them on line, so if anyone knows what i am referring to, I'd appreciate the help.
