Where is the low beams for a Honda CRV 1998?

I recently bought a Honda CRV 1998 and i can't seem to locate any low beam headlights. On the light selection, there's one for position lighting and then another for high beams but no low beams. Does this model only have the one light selection or is the low beams on a different location or something?

Cost of oil leak repairs?

I have a 2000 Honda CRV. I found out my car has been leaking oil from the top, left side of the engine. The leaking seems to be minimal and i haven't seen any on the ground underneath the car. I can't take it to a shop until Saturday because they're busy. I was looking for some estimates on how much it might cost to fix or what could be the problem in the first place.

What is this noise on this honda?

My mother has a 2005 Honda CRV and she has had it since it came out. She has never had a problem with it but now when she's at a red light then takes off there's a bad noise. It happens in the rear of the car. The noise is sort of a clicking noise.

Are K&N filters worth it?

I have a 2006 Honda CR-V in need of a new filter and I have narrowed it down to two possible choices. Pretty much all I care about is a clean, dust free engine.

This is an actual Honda filter:

This is the corresponding K&N:

Does the K&N offer $60 worth of performance? It's a CR-V, so obviously I'm not racing, nor do I care about horsepower, but I use my car everyday for work so I want to keep my engine running as smoothly as possible for as long as possible. Does the K&N do this or does it just give more intake? Because I'm not spending the money if it doesn't filter any better than the stock filter.

Also if there's another manufacturer that makes a better product that will keep my engine cleaner and running longer please feel free to leave a product number or a link.
