I'm assuming you've verified that your bulbs are actually good?

If indeed your bulbs are good I'd check the dimmer switch next but then again I'm going by 02 wiring diagrams. I'm also taking into consideration that you have not modified your headlights from the standard configuration. Keep us posted.

You are gonna think i'm stupid but no i did not check the head light bulbs... I may be wrong but i think it is highly unlikely they both go out at the same time... But i'll sure try it just to see.... I have not modified them in any way.

No, I think it would be highly unlikely that they would both go out at the same time as well but regardless it's the first step you need to take in troubleshooting your problem. Keep me posted.

check your low beam relay. if highs are working, swap the two and see if lows work

if not then either a no power to the relay or a bad switch

If the relay wasn't working properly he wouldn't be getting hi beams either but he did also mention he's already checked it.

Common problem with these trucks is the switch. I am willing to bet it is the switch. Try to wiggle the lever to see if you can get it to come on. Regardless, this is the most common cause for the lights to malfunction (other than the bulbs). Go to Autozone to see if they have the replacement part. They will verify how common this is.

Both probubly wouldn't go out at the same time. What happens a lot, especially with dusk or early morning driving (not really dark but dark enough for lights to activate) is one will go out and be undetected till the other goes out. Then you think both went out at once.

Ha i didn't think of it that way i'll try the bulbs then if nothing i'll try the switch... Thanks everyone ya'll are lots of help.

It was the bulbs all along... Last week i tryed an voltage meter to see if i had power to the bulb and i did so put to new bulbs and i got low beams again....
