Upgrade your Sierra / Silverado here
I installed Boost Auto Parts’ Ion Series illuminated door handles on my 2021 GMC Sierra AT4, and they’re a full replacement handle—not some cheap LED add-on. You get a ton of lighting behaviors (including sequential options), and the kit is labeled well so the wiring makes sense as you go.
Pros
- +Full replacement handle with OEM-style fitment
- +Multiple lighting modes including sequential signal options
- +Reuses factory passive entry connector (kept my lock/unlock working)
- +Harnesses and module outputs are labeled, which helps a lot
Cons
- -Running wires through the door boots takes time and patience
- -BCM tapping and clean cable management can be tricky to film/do in tight spaces
