I'm pretty sure the reverse lights are LED on the 2024 HD LTZ, but there not the brightest bulb for sure. I was going to order the Vled LED's for it. I had them in my 2018 1500 and they made a world of difference in light output. I removed a tail light on the 2024, and for the life of me I cant figure out how to remove the bulb. Any body changed there reverse light bulbs have any tips for removing the stock bulb? I was worried about breaking something so I gave up.

There is no bulbs.  Its an LED chipset.

 

You'll have to install auxiliary lighting.  Something like this would be an option - LPR REVERSE LIGHT BAR + UNIVERSAL HARNESS - CAR TRUCK SUV KIT

 

There is also those truck light bars you put under the tailgate, or you can do spot lights mounted in the step pockets or off the bumper.

Hard to believe there is not a bulb in there. There is a socket that rotates, I just was having trouble pulling it out and didn't want to damage the socket. I guess I could look into those pod lights that install into the step area of the bumper. I just find it strange that Vled's list a 921 LED replacement for the 2024 2500 HD.

That's because the lower trims like WT, Custom and LT have regular incandescent bulb tail lights and use a 921 reverse bulb.

 

The LED tail lights on 2024+up HD are full LED.  No serviceable bulbs.  That socket that "rotates", that's the connector end to the wiring inside the lamp to the driver module and the LED chipsets.  

 

Picture for refrence.  Also here's the microfiche from the GM Parts catalog for the 2024-up HD premium tail lamp (LT Midnight and Trail Boss/LTZ/ZR2/High Country).  You can see in the illustration that you can service the driver module, the truck to tail lamp harness and the license plate bulb(s).

I haven't tried to pull the bulb.

 

What I did is install a Diode Dynamics hitch light with back up. It is like a spotlight in reverse! It also gives you an extra brake light (my third brake light is blocked by my roof top tent).

The fitment Doesn't show the HD series. I'm assuming the C1R worked fine since you said you installed one, correct?

Yes, It is working great. I pop it out when the trailer is hooked up. DD has a little rubber cover to go over the connector when not in use. I drilled out the plastic mount and put my pin lock so no one steal it. The kit comes with a 2" and 2.5" mount so it fits in the receiver on the HD trucks. and other smaller trucks, it can be moved to another truck in minutes if you ever wanted to do that and leaves no signs that it was ever there.

 

It is very bright in all modes. Backup is amazing!

 

As mentioned before, I got this kit since I am blocking my 3rd brake light with my rack mounted tent. Our drivers are the worst so they need a bright red light in their face to avoid smashing into me!

 

The only thing it does is when I turn on the truck it senses something plugged into the 7 pin connector and thinks I have a trailer attached. I just ignore the message and it goes away in a few seconds.

 

Fitment was confirmed by Diode Dynamics tech support when I asked the question "Will this kit work with my GM 3500 HD?" The answer was yes and no need to cut or splice any wires.

      OCI, not when but why?

      By KARNUT · Posted

      It seems fine because it pulls everything out of a hot engine. I’m not going to worry about a thimble full with 5K oil changes with synthetic oil. Every other oil change is at Honda they pull the plug. I watch them through the process. It turns out going to Honda what amounts to their normal oil change intervals.

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.
