hay, i need an advise from expert.... installingfog light that eats 55W on each lamps, will it draw too much power and overload the battery? and what is the wattage of the facory fog lamps?
thanks!!

 

I'm no expert, but I'm quick...
The factory fogs are 12v, 55watt, H11 bulbs.

 

Don't confuse wattage with volts. Volts would be the "pull" you are concerned with and since watts = volts x amps, your likely "pull" is only 5.5 volts at 10 amps, hence a 55W foglight system.

 

Wouldnt that be 55W/12V=4.58A? Voltage should be constant.
(Or, 55W/14V=3.93A, voltage is closer to 14V when the car is running)

But perhaps I'm a bit off, its time for me to head to bed

 

Considering the fuse for the circuit is 10amps, the total draw per light may be the 5amps you are referring to.

As for 14v, the alternator only spools that high to charge the battery at peak. Normal flow to the battery can be as low as 11v or at continuous, 13.3v. Most round up to 14 as an absolute output.

 

thanks Experts!!!
if facory fog draw 55W/lamp then my PIAA shall be okay... it is also 55W/lamp and it's not over facory one..
thanks!!
