I respectfully disagree. My headlights are amazing and I have halogens at a fraction of the price of retrofits (I'm guessing the OP needs to save his money for some repairs right now).

I've tried a few different combinations and this is what's worked out the best:

New TYC headlights - $80 on Rockauto.com. The old headlights, especially 96-98, lose their ability to reflect light on the road over time. New housings is literally like night and day. Just be sure to adjust the beams after you put them in.

Upgraded wiring harness & 100/80W bulbs - $30. Yes, 100/80W. If you change the wiring setup by adding a pre-made relay harness, it's no longer running the power wire from the headlight stalk in the interior all the way into the engine bay and to both headlights. That wire just become the power wire for the relay with then draws power straight from the battery. No more voltage drop. The harness allows you to safely run 100/80W Hella bulbs. Let's just say I can see everything now with 100W high beams.

Amazon.com: H4 LED Headlight Wiring Harness [Negative Switched Conversion] [Fused] H4 Head Light Relay Harness Kit for 9003 H6054 H5054 H6054LL 6014 6052 6053 Subaru Toyota Head Lights: Automotive

So for $110, you can have fantastic headlights that work better than when the 4Runner was brand new.
