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!

Alright, before you say you don’t hear anything let me explain first. This video posted below is my 2021 Trail Boss 3500k miles and has the most annoying exhaust sound. I know there’s some serious pro’s on here who could tell me what’s going on.
Essentially any time I start it up high RPM, accelerate, or decrease RPM’s I’m greeted with this annoying metallic rattling noise coming from exhaust.
Took it to dealer who claims it’s normal (per-usual) and says it’s the liters I can hear in the exhaust tone. They checked exhaust donuts and heat shields and found no issue.
However you can hear a rattle and what sounds like an exhaust leak. Was told it’s a flapper but it’s not, flapper is toward back passenger side. This is front passenger side.
I could best describe it as escaping air coming from somewhere near the manifold I’d assume. Almost like a metallic farting exhaust noise for lack of better description.
Videos to follow of noise while commuting.
Forgive me if this question has been discussed but I could not find anything with a search.
I have a 21 Trail Boss that I want to lift 4" for a total of 6" to fit 35's. I have been looking for awhile now at the available lifts specific to the Trail Boss and AT4 and have narrowed it down to two...
The BDS 1805H strut spacer lift with UCA's.
Rough Country 27550 with their Vertex damping adjustable coilovers.
The cost of the kits are within a couple hundred dollars of each other.
I have watched all the reviews I could find on the Vertex coilovers and they seem to be good. I like the idea of them but I understand they can't be rebuilt so if they fail out of warranty I would have to replace them. Add to that the general sentiment that Rough Country in general isn't necessarily the greatest in terms of quality makes me very uncomfortable putting the kit on my truck.
BDS on the other hand has great reviews and a stellar warranty but I only get a strut spacer lift with new UCA's that retains the factory coilover with the Rancho shocks.
What are your thoughts, opinions and or experiences? Your input is much appreciated!
