First thing you bought for your new truck...

Besides a few minor things, badges, antennae, dividers, etc., the first purchase...

side steps.

[krackkkk]

My first purchase was a dash cam to be honest. First real purchase will likely be a tonneau in the near future though.

Glad I read the post above, I forgot about the license plate bulbs being switched to LED on day one lol. Also the organizer trey for the console as well. How they decided to put LEDs everywhere except the rear plate is beyond me.

Every light on the truck is LED except for the license plate bulbs. I don’t understand why they would not put LED’s there unless they didn’t want the lights to wash out the reverse camera. The LED’s do not wash out the camera just an FYI.

Yeah, every bulb on my truck are LEDs now. However, I do wish some were brighter. I put some 720lm LEDs in my reverse lights on my 16 Silverado. Wish I could do the same here. Helped the camera a lot at night.

Boostautoparts.com sells a reverse lights mod that is easy to install. I have it installed on my truck and I’m very happy with the results. They also have YouTube videos showing the install and the results.

There was one more thing that I left off my list. GMC Logo Puddle lights is a nice little mod that is easy to install and makes a difference

I thought I read somewhere on here that the reverse LED lights werent able to be changed. Is that not accurate.

The Putco LED blade light that goes between the tailgate and bumper doors a really nice job of lighting up behind you when in reverse.  The whole thing goes white.

Yeah I almost purchased one of these but decided against it in the end. It looked/worked great on my 16 Silverado but didnt think it would on the 21 Sierra. The depth under the tailgate on the 21 is much deeper. Saw one running down the road and it barely put out any light til I got up on it. After seeing that, it just wasnt worth the $300 to me.

Yes you can. The ones that came stock on my truck just aren’t bright enough for my liking.

Well then, I may be looking at Diode Dynamics again. Loved the 720Lm ones on the old truck. Those were nice and bright.
