DRL,lights

Can these be added if not an already option? I have an 05 and my wife likes them . OR are they on all trucks and mine is disconnected ??

From what I've read, it's tricky to add OEM DRL's if the option was not originally included in the wiring of the truck. I'm in the process of adding an after market DRL to my 06 DC made by Lite-Minder. Lite-Minder Web Page It can add the DRL feature to low beams or fog lights. It has an optional power reducer to run the lights at lower output. I hope this helps.

THANKS!! Let me know how it turned out and ease of installation..

Here's how I made out with the Lite-Minder DRL relay. It worked fine with the low beam lights, but blew its 20A inline fuse every time the high beams were activated. I burned out 6 fuses trying to get it to work. The supplier advised I bring it to a mechanic. Yeah, right! So I connected the relay to the fog lights, instead.

It works now and gives the added benefit of being able to have your fogs on with any other light configuration: no other lights, parking lights, low beams, and high beams. For use in real fog, the low and high beams kind of defeat the purpose being on at the same time. Added light reflection.

If you use the included resistor to lower the output of the bulbs, you will have operation closer to the manufacturer's design; bright fogs with your low beams and dimmer fogs with every other setting.

I'm satisfied. It remains to be seen how long the bulbs last being on continuously.

Basically, it's easy to connect. Four wires: one to battery, one to ground, one to hot wire or fuse with ignition on, and one to the hot wire of the light. The resistor is cut in to the battery wire, if desired. The relay can be screwed to the cowl or double sided tape works fine. It's very light in weight. The resistor should be screwed to a metal surface as it gets very hot. Another reason I'm not using it and burning the bulbs at full strength.

Can you post or send me a wiring diagram?? thanks.

Here's a wiring diagram:


Adding the Power Reducer allowed me to wire to the low beams without blowing the fuse when using the high beams. I really don't understand the relation between the two as far as power draw is concerned. The fog light setup worked with or without the Power Reducer.

Although I liked the idea of being able to use the fog lights without having to have the low beams on, the low beam DRL setup conforms to California law. I don't have a heavy fog problem where I live anyway.

I have a question about the setup shown above. The low beam wire is connected. There is no wire connection to the high beam. I just discovered that when I turn the high beam switch to the on position, the DRL's go off. This is with the regular lights NOT on, just the DRL's.

How can anything else control the current running in a separately wired system? The DRL's are not physically connected to anything other than the battery and a hot ignition wire (plus ground).
