Headlight Problems

I have a 2002 cc lb xlt F-350. My headlights stay on all the time. I think it's due to the how long it is or something. But does anyone know how to make the lights come on when I want them to?

My main reason for doing this is sometimes when I cycle my glow plugs and then start my truck the right one only fires sometimes. I want to say it's because of how much energy it takes to start the engine an keep those suckers fired.

Any ideas or things I could try? Or maybe where I could get a wiring diagram or a fix for why one doesn't fire consistently.

I'm lost, when you cycle the glow plugs your headlights go out, or just when the starter engages?

They are always on the momentarily go out when the starter is engaged to start the truck I think it consumes a lot of the voltage. Once, the truck is started the lights come back on, but sometimes the right light does not re-fire.

Which is why I would like to wire the headlights so that they are off all the time and I can manually turn them on after I start my truck or so they are off when I'm driving around town during the day, just seems like less wear and tear.

What the hell are you talking about?

Do you have day time runing lights?

Or Auto headlights?

If you have auto lights, just turn them to the off pos.

You have everyone scratching there heads.

I do not have Auto headlights.

My headlights are always on, even in the off position. I think it has something to do with it being a crew cab long box, because it came with a back-up beeper that I had to yank out. So it must be a size issue. I'm actually kind of surprised that nobody else's lights are always on.

I think it's more of a safety thing, but I want to make to where they actually are off in the off position and then I can move the switch to the parking and on position.

Just throwing it out:
Is there a relay for the headlights? If so, could the relay be bad leaving the lights on?

Your truck has Day Time Running lights, more then likely it came from Canada at some point.

The DTR module is between the drivers battery and the head light. Unplug it...

You forgot to mention in your thread that you have HID's... And part of your issue with them not lighting back up, is alot of time the DTR lights are at a lower voltage then standard headlights. So there is not enough voltage to fire the balast again.

No relay... But thats a great mod to get more light output from your factory lights.
