Hello All,

 

New to this site, just bought a new 2021 Silverado LT Trail Boss a few weeks ago. One of the first things I am doing to this truck is upgrading the few halogen bulbs that GM decided to keep on it. The Rear backup and license plate lights all went super smooth, no issue. But when I went to remove the front blinker bulb from the housing I was faced with a different configuration than what I've seen. The place where you would normally find the circular grip for twisting out the bulb has a small hex head there in place, and it does not look to actually come apart (Please see attached picture). I think that I might have a different blinker than what normally comes with this trim (and I think it may already be LED) but I am unable to find anything online that resembles or mentions this configuration. I am only able to find the typical bulb backing which does not match mine.

 

Does anyone have insight to this or possibly know what kind of blinker I have? I have included a picture of the back of the blinker as well as the light housing itself as I think it too looks slightly different than others I have seen.

 

Thanks in advance!

DUDE!! Thank you!! I was not planning on getting a midnight edition but due to current stock, it was the only options they had. I knew some of the items the package came with but did not know that it changed the front blinker lol. I had been looking up every other reason for the difference besides midnight edition.

 

You rock!

You're welcome.  I wasn't aware that midnight edition had different headlights until a few months ago.  One of the things midnight edition got were HID LED headlights that have LED turn signals, same as the LTZ and High Country trucks.  Trail Bosses without the midnight edition package got non-HID LED headlights with halogen turn signals.

Yep Midnight LT Trail Boss gets the LTZ/High Country full LED lamps.  One less upgrade to make!

Yeah didn't know HID LED Headlights meant the upgrade to the blinkers. Now just have to try to return part of the package I got from Lasfit. Got the LT Trailboss package that came with LED's for license plate, backup lights and Turn signal. Awesome lights btw, the backup lights are insane. Now I'm seeing if I can just return the blinkers since they were the majority of the price. I'm sure I'll be able to work something out with them. I was dumb for not checking before hand, but everything I saw with Trail Boss' online were the same.

Just the High Country and Midnight Edition LT TB get those headlights. LTZ has the same ones as LT & RST, with incandescent turn signals. I put the LASFIT LEDs in mine.

Yup. Mine have lasted two years and still going too. Pretty impressive. Lots of crappy LED bulbs wouldn’t live half that long.

Yeah, the backup lights are intense. Love them, makes a great light for the reverse camera.

They are on the more expensive side of LED's that you can buy. But they are definitely quality. Which is what I'm going for on the new vehicle. And the price isn't insane, just compared to LED's that you could buy.

If you want to take that reverse lighting to a whole new level, GM Accessories has that Putco blade lightbar for under the tailgate.  It has red flag leds for turn signals, and uses those same leds for an additional stop light.  However, when your reverse lights turn on the bar lights up in the same bright white the LasFit led reverse and license plates are.  It's a whole strip of white light that really lights up the area you're backing into.  The camera on these trucks really catches it, too.

Thanks for the info I just spent 30 minutes trying to muscle the back of the existing LED housing out. Glad i stopped to look and see what someone had to say.

    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
