anyone know what's wrong with my headlights?

I just bought this problem, 00 ram van 3spd v6 off my friend. I know they were working about 8 days ago.
He told me that the headlights were flickering, and now do not come on... he didn't know what the problem was. they are infact, not working.
I tried looking to see if there was an exclusive headlight fuse, but I couldn't find anything in the 2 locations known - left side dash board driver side, and next to the battery. all my other lights work properly.

 

It was the headlight switch. pulled the panel cover, removed the 3 screws, disconnected the old/existing switch and saw that it was a little burnt at the connectors.
$30 at autozone, sw220.
it's new things that I am going to learn about this van that'll make me love it.

 

Might check the head lamp sockets for corrosion. And see if the wiring there looks like it has tired to get hot.

 

^So I need to replace this switch and get it at a local parts store, or autorock?

And yes, my skin tone is the same color as the SUN.

 

I have a 97 ram sport 1500 w/260,000 mi and I have an ongoing headlite problem. They go out! The first time I replace the switch from LMC. Lites went out about a year later so I got one from the dialership. Lites went out again in about 6 mos. Replaced it with the one from LMC untell..yep, out again! My truck doesn't have a relay. My machanic wired in a relay about 6 mos ago and was doin fine untell last weekend. Any ideas? David

There is an auto-resetting circuit breaker built into the headlight switch. Something in the circuit must be overloading it. Do you get water inside the headlights? How old are the bulbs?

 

A bad/weak ground on the body near the headlamps will also contribute to overheating the switch and circuit breaker within. The ground for my passenger side headlamp was right next to the light, for the driver's side, behind the battery.

I removed the headlamp current from my headlight switch.

The original High/low beam wiring now activates relays which pass the current through thicker wiring and a much shorter circuit path, and I get another 2+ volts at the bulb, and a whole lot more light output.

 

After having an intermittent passenger headlamp for the past year, I finally picked up on a bad headlamp socket after changing the bulb in the faulty side once, without fixing the problem. WHile checking for a replacement socket with NAPA, they list a hi-temp and standard socket. I just bought two hi-temp sockets, and will check the grounds when I replace them soon. I also think they are not very bright, so maybe the ground is the issue. Thanks everyone for the good information...
