They do cast a fair amount of angled light on either sides of the truck. Take a look at the last pic on my original starting post. That pic is taken from the drivers seat looking back through the side mirror...

But you need to do this simple mod if you want more light down the sides of a trailer...assuming you have the towing mirrors with the LED lights? Now these LEDs in the mirrors will come on every time you put it reverse...

Under the drivers dash, locate the Body Control Module (BCM). Install a diode (jumper) between the two pins (see pic below). Jump from the brown BCM pin (brown/blue wire) to the second from left pin in the pic (brown/white wire) of the "pink" BCM. The gray stripe on the diode must be on the "pink" side. Simply push it in approx 3/8" to 1/2" deep. The diode is a Radio Shack part Number 1N4004. I believe a 2-pack is about $2.00.

Thanks. 
i have bed lights so have the switch in the cab for the mirror lights. Im going to wire them to that so i can toggle them on/off. 
i dont really want them blinding me as i walk up behind the truck and unlock it.

Do you have any details on wiring it to the the bed light switch? I have those as well and would like to go that route.

    • On 2021 3500hd it consistently sets automatically when selecting park if the incline/decline is above a certain angle. 
    • Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks. 
    • Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions? 
    • 2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!  
    • Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
