If you look on the side of your headlight module you will see a big empty square spot (normal led) or you'll see a silver something bolted to that spot.  It looks like a normal HID ballast.  Huge difference at night.

There is legit 3 tiers of headlights on T1 trucks.  This is not a joke.  Straight from the order guide:

They aren't an HID LED, they are just a higher intensity LED lamp.  They are both of the LED reflector design, just the LTZ/High Country and Midnight LT TB get a better version.

Was just arguing the semantics really.  No such thing as HID LED :)

 

Wonder if the unit shown above is the LED driver? I have the midnight package so need to head out to my truck later and look

Don't know if it's the driver or not.  I've seen it listed as LED Headlight Module Ballast Control Unit.  Never heard of an LED needing a ballast.  Very similar part for the HD with high intensity LED lights.

Those part numbers come back to a Ford Edge for every listing except for that one.

Appears that is what I have here though.  HAS to be the driver for the 3 LEDs and however many go into the DRL

Side note... I was questioning why it would be such a large driver with ~24 pins when I originally posted.  After a few cervezas and making a post about pulse width modulating some of our lights, I realized why.

 

The DRLs and lowbeams/headlights are likely run off of this (way too cold and dark to check).  In addition, the DRLs are PWM so the circuitry involved is likely large and they need to contend with heat, in an engine bay, for the life of the vehicle.  I'd bet the farm this is a SET of drivers for the headlights, turn signals, and DRLs

This now has me wondering if the Midnight Edition TBs have LED turn signals?

The one I looked at did.

It has been a couple of months but it looked like the same headlight setup as the High country. I'm going to try and look it all up

      2027 GMC Sierra: Official Discussion

      By Jake87 · Posted

      Bro, you still got that truck? I'm not seeing any m rust or flaking, which rusted metal flakes. Everyone thinks the wax "is rusty" but it absorbs its surrounding environment, creating a hard, natural shell that you can literally shoot with a bullet and won't flake off. It'll last 50 years like that as long as the barrier isn't compromised by getting in a wreck or meets a chemical that disolves wax. My 09's frame is even duller looking than that, and is holding up better than my rockers or 3rd set of painted shocks.

      auto mechanical driver's door unlock without pressing button? [2026 Silv. 1500 WT 4WD RC SB 2.7L]

      By newdude · Posted

      No.   That would be an LT and higher trim.  Passive entry.  There would be a little button on the door handle and you can program it to proximity lock or unlock.     WT and Custom do not get this feature.

      Mediocre, how much did they lose on the poorly conceived EV strategy?   I wonder how much the stock price is being 'inflated' by all the buy-backs?   Cadillac literally looks like a brand without a rudder, no clear goals or product direction - performance or luxury? I guess performance because we can throw a small block in whatever we can and call it a day. Certainly not luxury when a Denali or High Country is reasonably cross shoppable. The Celestiq - no way - no vehicle can command quarter million prices when something wearing the same badge is on the buy here pay here lot across town.   Notice the 'base' Escalade doesn't even come with the 'leather-appointed' seating surfaces.   Hummer EV - fail Silverado EV - fail Sierra EV - fail Bolt/Volt EV (The most successful EV cancelled, restarted, cancelled, whatever its current status it)   Hybrids - none Sedans - none Medium duty - not anymore Minivan - none Coupe - none Convertible - none CUVs - 20+/-   6.2 Recall that landed squarely on the GMs highest seller - and specifically the fattest margin higher trims of the Yukon, Escalade, et. al. The most critical product line they fumbled big time. In the Escalade segment, are those buyers forgiving GM for a bad engine and patiently waiting for the fixes and dealing with the headaches? Nope, they dump them and go straight to the other premium brands.   In the ENTIRE GM portfolio how many aspirational vehicles are there? Corvette, Escalade (quickly being superseded by the obvious better value Denali)...   I posted somewhere else... what if Cadillac left the luxury game and became a performance brand similar to AMG or (gasp) Ferrari? Cut all the entry-level and base models from their line up and focus on the V-series or Blackwing or whatever they call it now. Of course, those would have the pre-requisite luxury and technology as standard equipment. This opens the floor for Buick to step in/up as the luxury brand (like they are in China), no 'performance pretenses' get rid of the 'entry-level' models with equally 'entry-level' power trains and become the Maybach to Cadillacs AMG. With those two brands effectively out of the way Chevrolet, the 'entry-level' brand has the floor to itself and GMC can take over as 'professional grade'.    Now each brand has a focus, no in-fighting, clear direction, and customer targets.   Just need to sneakily slide Corvette into the Cadillac brand and dump the vestigial script writing.

      I can't get enthusiastic about the 1.5T (or the 1.3 or the 1.2), I won't drive a CVT. But the stupid things sell in volume.

      There is a big difference in motorcycles and vehicles - nobody needs a motorcycle, they WANT one. That WANT is the most powerful force to drive price upwards.   I've hated every iteration of the Equinox, a prime example of GM laziness. It excelled at absolutely nothing, barely competitive by every metric. At least the latest generation looks decent.    I want to like the Buick Envista, but that pitiful engine plus FWD only is a BIG NO for me, I don't care how good it looks.
