I am a little confused by the previous posts on this H4 upgrade...I need clarification.

I have installed the H4 headlights with the bulbs out o' th' Hella box (55W/60W I think?) and was not aware that the relay had to be installed unless higher wattage bulbs (like the 80W/100W) were used. (Higher wattage bulbs are illegal for street use) I also thought that the USA stock sealed beam headlight units were about 55W as well...which would then make sense not to need a high power relay. I guess my question is...

What is the maximum wattage H4 Halogen bulbs that can be used without a relay?
