Here's my prescription for maximum performance lighting that looks bone stock but can be had for only about $150 total:
1) Upgrade the stock Jeep wiring with three relays and heavy wires. I feed each pair of 100w lights with a 10 gauge fused wire directly from the battery and each filament gets a 12 gauge wire and 12 gauge ground, ensuring maximum brightness. Stock headlight wiring is 18 gauge and stock foglight wiring is 20 gauge, and all of the current flows through the headlight switch with no relays - and you don't want to damage that switch.
2) Replace the headlights with Cibie H4 reflectors and Narva 80/100w H4 bulbs. The 100w high beams are tremendous. I use a pair of relays operated by some male spade lugs inserted into the original headlight connector - the original wiring is intact.
3) Upgrade the stock foglights with 100w H3 bulbs. In this case I used Sylvania bulbs from the auto store, Sylvania is owned by Osram. The lenses get warm with 100w but the plastic housings are OK - the beam pattern on the stock fogs is excellant. If it is present, you will need to trim off the small square tab on the 100w bulb to fit the 55w socket - I used a Dremel cutoff wheel but there are other methods. Once again I inserted a spade lug in the original foglight connector to pull the relay.
4) Bend over or cut off pin 1 on the stock foglight relay - this relay forces the foglights off when the high beams are on - bending pin one and replacing the relay allows complete driver control via the foglight switch.
5) Remove the foglights and note there is a second square hole in the bumper forcing the aim to be straight ahead. Cut or file off the tab on the lamp mount that goes in the square hole. Now re-mount the lights and this time aim them about 20 degrees outwards from straight ahead - you just got a field of view 40 degrees wider at night, with some foglight pattern overlap still remaining in the center.
This prescription gives incredible lighting performance with no visible differences from stock to attract the attention of theives while parked or law enforcement when in use.
For offroad use, I use a combination of 100w high beam headlights and 100w foglights - really bright and light everywhere. Around town you use the 55w low beams with the option of foglights on or off.
