lighting

What is the wattage of the:

Front headlights?
Fog lights?
Light bar?

What bulbs are each of these using?

I know nothing about lighting... So anything and everything would be greatful!

what year liberty do you have?
The bulbs are listed in your owners manual. Online manual at jeep.com/user section
If you want to upgrade headlights and get better brighter whiter than stock Use PIAA extreme white plus 9007 bulbs.
For better than stock 42 watt fogs , do the 65 watt mod using silverstar 9005 requite mod tab trim (easy)

Light bar dont have one...owners manual...

Here's a list of every type of light bulb in the KJ : http://jeepkjcountry.com/forum/showthread.php?t=44420

As far as wattage goes, I'm not sure but you could probably Google those bulbs and see what it gives back for wattage. Or find one of the bulbs at your local auto parts store - it may say the wattage on the packaging, not sure.

9007 headlights are a standard 55/65 (low/high). As mentioned above the fogs are 42-45w 9145s and are easily replaced with a 9005 bulb (which is a 65w high beam in a dual-headlight setup). Not sure on the light bar as I've never had one apart, guessing they would be in the 45-55w range.

ITBJRC the light bar uses 35w H4 bulbs

Shouldn't one be concerned with throwing 65w bulbs onto a harness designed for 45w?

inb4tjkj2002says"beendoinitwith100wforyears"

I wouldn't...

65w / 13.8v = 4.71 Amps
45w / 13.8v = 3.26 Amps

A total difference of 1.45, or nearly 1 1/2 amps. Nothing to worry about. The wiring to the fogs is over sized and fused for more than that anyway.
