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!
I recently had a 7.5in vertex lift installed on my 2011 Silverado by a very reputable shop. Truck looks awesome but my mpgs took a major hit. Only fill up with premium. I know trucks aren’t known for stellar gas mileage but going from 15/18 to ~11 mpg is a killer.
- 5.3L with Diablo afm disabler used to prevent oil consumption (it works).
- 18x8.5 in wheels with 275/65 duratracs (nitrogen inflated). 2in spacers all around.
- K&N air filter.
- new plugs and wires with ~30k miles on them.
- flowmaster super 44 dual exhaust.
I’ve cleaned the throttle body and MAF. Hooked up my obd II and no codes.
Other than removing the lift what can I do?
Thanks in advance!
