for every watt saved..how much is that in fuel? I know the headlights are the most dramatic, but to add up 21 external lights alone..yikes man, I don't think my 18 foot long delta 88 had that many lights... 
there is little lights next to big lights on the old sube... trying to be pretty I guess. |
This certainly isnt an accurate of a method, but it was enough for me to justify swapping my car to LEDs.
Givens:
1 Horsepower= 745 watts.
a "normal" produces approx 10HP to cruise at 60mph
Calculate how many watts you save by switching to LEDs and figure out what fraction that is of a HP. If you know how many HP it takes to cruise at 60mph you could make a rough guess at mileage gain.
