Price: $90.00
Pros: Bright
Cons: Expensive
Recommended? No

Comments: I'm only NOT recommending them based on cost.
Over wattage bulbs REQUIRE the additional expense of a heavy duty harness.
That being said, the Fatboys (and Rampage housings) are MUCH better than stock.

After 2.5 years, one of my low beam filaments died.
Since MOST of my driving is in well lit suburbs, I decided that $90 was too much so I opted for $50 Silverstar Ultras.

As a test, I only replaced the bad Fatboy.
Shining up against a wall, the Ultras are a BIT whiter, but while driving the Fatboy washes out the Ultra. You can tell the Ultra is there but the Fatboy is doing most of the work

I found some Osram 100/90 bulbs on Ebay for less than $20 shipped (!) so I think I'm going to order them and return the Ultras...

(Edit: I just noticed that the picture at the top of this page differs from what my bulbs look like... Maybe I have Fatboy 2's??)

Price: $160.00
Pros: The power of the sun in your head lights.
Cons: The people driving in front of me don't like them.
Recommended? Yes

Comments: Awesome bulbs. However, I didn't upgrade my harness after the install, and after three months I had no headlights. Mistake on my part.

When you buy these, buy an upgraded harness as well. I got the ARB wiring harness and now they work fantastically.

Pros: Very very bright.
Cons: None yet.
Recommended? Yes

Comments: Bought the KIT (price includes the H4 conversion lens). Very bright, haven't had to replace since I installed the kit (but it's only been a few months).

I would recommend buying the loom - the stock connector cables were not designed for the increased battery draw.

The difference between this and stock is almost literally night and day.

Comments: Got em for christmas, so I don't know the exact cost. Got the H4 headlight bulb housings with the Fatboy bulbs. Incredible improvement from stock headlights. Ordered a beefier harness online, and did the install myself. Super easy, one of my best mods to the jeep.

Pros: Very Bright
Cons: $$$ but you get what you pay for
Recommended? Yes

Comments: They really shed some light on night time driving. They are bright enough to blind oncoming drivers. Some readjustments were needed to avoid having everyone flash their high beams at me. almost never have to use my high beams.

Price: $79.00
Pros: Bright!!
Cons: Don't last nearly long enough
Recommended? No

Comments: Disappointing lights for the money. Sure, they are bright. However, to last less than two years at that kind of price is a ridiculous.

Good luck even getting a question answered from IPF's "customer service" department. They were useless, in telephone or e-mail form.

Comments: These produce some truly awesome light. The low beams are almost too bright. My main beef with these is they cost 80bux and will last maybe one year. I can't afford to replace these every year!

Recommended? Yes

Comments: These bulbs are AMAZING. I used to run 130watt KC driving lights to compensate for the Silverstar headlights i had that didn't light up very much. After I installed the Fatboys w/ IPF lenses, I can't even tell if my 130w lights are even on. The packaging says this combo gives an optical equivalent of 190w (but only uses 60w low beams), and I believe it based on my experience with them. I did not replace my wiring harness either.

IPF Fatboy H4 Bulbs
Price: $85.00
Pros: Bright, Easy to install.
Cons: An aftermarket HD harness should be used with the Fatboy Bulbs
Recommended? Yes

Comments: I've got the IPF lenses with the fatboys, and a HD harness.

I still have to aim them down some, but let me tell you, they are BRIGHT! IMHO headlights are a safety item, not a place to skimp.

I can't even tell the difference when my factory fogs are on or not. Both lowbeam and highbeam settings have a very nice beam pattern, and the lowbeam cutoff is perfect.
