They fit the 2014–2018 GMC Sierra 1500, the 2019 GMC Sierra 1500 Limited and the 2015–2019 GMC Sierra 2500HD / 3500HD, on trucks without factory LED tail lights. Quick check: if your Sierra is one of those and its factory tail lights use bulbs, this is your pair. Does not fit: 2019 and newer Sierra 1500 other than the 2019 Sierra 1500 Limited.
In-stock orders ship the same business day, and delivery takes 3–5 business days after shipping. Shipping is free to the contiguous U.S., and each item ships separately with its own tracking number. If it's out of stock, the estimated ship date is shown under the price.
Yes. 2016 and later trucks plug straight into the factory connector, and 2014–2015 trucks use the adapter harness included in the box — no cutting or splicing. CANbus decoders are built in, and everything needed to prevent hyper-flash and dash warnings is included — built into the light or packed in the box.
The turn signal works the way GMC built it: brake and turn share the same red lighting zone, and the signal flashes red — the same logic as the factory lamp, in line with US lighting regulations. A startup animation runs each time the lights power on.
Yes to both. A red light element wraps the outer edge of the housing, with the reverse section set in the middle of the lamp. Behind the smoked lens the rear stays dark with the lights off and reads red the moment the brakes come on — the factory outline with a smoked red LED build inside it.
Yes. They're built on patented optical technology and independently tested for vibration, mechanical shock and corrosion resistance. The UV-stable lenses won't turn yellow, and every pair is covered by a 2-year warranty.
A little moisture right after install is normal. Humid air gets trapped inside the housing, and when the lights are first switched on it can show up as fog or small droplets. With regular use it clears on its own, usually within about a week, and it can also appear for a few days after a car wash, rain or a big temperature swing. If it's still there after a week, contact us with your order number and we'll take care of it.
