Hey everyone! I'm new to this site and just got my 2017 Silverado LT 1500 last week. I did a search on this topic but came up empty. I love the headlights with the LED switchback strip on the LTZ, Z71, and High Country. I was wondering if anyone has tried or considered putting those on an LT package. Are the harnesses the same so it would be a simple plug-and-play or am I just having wishful thinking to think its that simple. If not plug-and-play, what kind of modifications would have to be done (or potential harness replaced) to make these lights work?

 

Let me know your thought, concerns, or problems this upgrade may have. And if anyone has a picture of the wiring harness of the switchback LED strip headlight and could post it so we can compare the 2 to see if they are the same or even similar and what differences there are between the two headlights. Thanks in advance!

I have done this upgrade! I have a 2016 LT and didn't know there was a difference in the lighting between LT and LTZ until after the fact. So I began my quest to see what else was different between LT and LTZ. You won't need a new harness but you will need resistors, otherwise, you'll get hyperflash. I built my own Plug and Play harnesses with inline resistors.

I've also added the DL3 Mirrors which have the turn signal, puddle lamps, power fold, auto dim.

 

Thread on that here:

I did the LED Tail Lights and Heated Steering Wheel.

 

And Auto Dim Mirror -

Just what I was looking for, thank you! What wires did you have to splice into for the resistor? And do you have a thread for the LED tail light upgrade?

You'll have to tap the turn Signal circuit and ground for each side.

 

For the tail lights, I bought a PnP harness from Gen5DIY. If I recall, it was $80.

 

For the headlights, I believe their PnP harness is like $100... Since my recent harness projects, I decided to make my own.

 

If you decide to do this upgrade, PM me.

how much were the liz upgrade lights? and where can i buy them?

I've been looking on ebay for some and it looks like for a pair they are in the ballpark of $1200-$1500. Pgamboa bought his LTZ ones and immediately sold his LT lights and had very little out of pocket money.

    • You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling. 
    • You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built. 
    • Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
    • Thanks for posting, I'm sure it will help someone
