55 watt PIAAs only draw about 35watts..
the rating on the lights are usualy a "Equivelent of" wattage for noraml lights.
If You want high light output for low wattage/amperage, then the best way to go is LED.
check out the VisionX (I think)
Do a search for Xmitter lights. that'll get ya in the right place.. lol
many different styles, sizes etc etc. But theres all the lighting info you would need to see.
We put a (I think) a 36" one on my bosses 2009 chev.
It completely drowns out the headlights and all. Go blind looking at the thing in daytime.. lol
but you can get em smaller or bigger, double or single row etc.
you should be able to go on there and think "I want to use 70-80 watts for my lights." then go down the lists n all and compare n find the lights you want..
Here, showing the lil solstice lights...
