Hi all,

 

I am over in Australia with a converted AT4 so there are no dealers or colleagues to seek advice from so apologies in advance if I am missing something obvious..

 

I have Google extensively bulb upgrade for my high beams as they are pathetic on country roads. The very limited information I can find suggests to me there are very limited options. 

 

They appear not to be HID bulbs? I can see limited options if they were HIDs.

 

Any advice/options/part numbers for what I suspect are LED bulbs please?

 

I have also researched a behind grill light bar but this is also troublesome with the active grill shutter. 

 

Thanks in advance.

 

Dane

They are LED without a replaceable bulb. You are stuck with it.

 

Add some auxiliary lighting.

I would suspect, that like the Chevrolet, they are LED bulbs.

 

My goto is Diode Dynamics, but they don't list any upgrade options for headlights or fog lights.  Unlike my Chevrolet, where the fog lights can be replaced.

 

Sorry that I couldn't help.  Good luck.

Howdy all, I have a 2020 GMC Sierra Elevation and came here looking for an answer to this exact question. I apologize in advance for asking this, but what I see from the thread above is the headlights are an LED unit and are not replaceable with something brighter? I can live with the high beams the way they are but would love to have brighter low beam headlights. And just out of curiosity what happens when a light burns out? There must be a replacement unit? And would there not be someone who makes a brighter unit? Thanks a lot and happy motoring

No, you really can’t simply replace the “bulb” with something brighter. It is not your traditional bulb you are used to and not meant to be replaced. LED last for 10s of thousands of hours and are not likely to burn out in the average life of a truck. If one did burn out, you must replace the entire headlight assembly. 
 

I have no idea what’s out there on the aftermarket. There are likely aftermarket replacement headlight assemblies but anything that isn’t junk is going to be very expensive. To my knowledge no one makes any kind of modification for you to put in the housings already on your truck.

      OCI, not when but why?

      But Grumpy I did show several subdivisions that had homes starting in the 170K range. If you bought a Townhouse or Condo you could go cheaper. Same with a car 3000 dollars in the 70s translates to around 20K today. There are several models at that price. You actually get more for the money. In the 70s I drove a 3000$ car bought a 28K home and made 4.50 per hour. Thank goodness for overtime. Today I could buy a 170K house drive a 20K car and make 25 dollars an hour operating the same machine today. The difference the house, car, machine would be better and have AC. And I wouldn’t be taxed on overtime. And statistically your wife works too. Easing the burden. I thought we agreed to disagree. I brought receipts earlier, showing examples. I think you’re more stubborn than me. I was done with this debate.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.
