Features Plug-and-play compatible with GMC Sierra HD 2020+ fender lights Dynamic startup sequence with animated effect Fully-illuminated housing, with dual-lens design for an even glow Optional Sequential turn signal feature, with plug-and-play wiring harness OEM-grade construction and perfect fitment Engineered and assembled in USA Overview Upgraded Styling. These LED sidemarkers are a plug-and-play replacement for the factory fender lights, illuminating the entire width of the housing for a distinctive look and brighter appearance. Choose from three lens color options to get the look you're after. Unique Startup. Both the standard and sequential models feature a unique startup sequence. Every time the sidemarkers turn on, they illuminate in an intense amber color starting from the center then spreading to either side. Once they are completely illuminated, they gradually return to a running light mode. Sequencing Turn Signal. Our sequential option provides an upgrade in functionality. Anytime you hit your turn signal, the sidemarkers illuminate in a sequencing amber pattern to indicate signaling! The sequential option uses the included plug-and-play harness to power the fender lights using the headlight connector. Options Amber: These match your original sidemarkers, and are DOT/SAE compliant. Smoked: A dark appearance, great on black and grey vehicles. Clear: These are clear in color, but still have the retroreflector optics.This Part Fits:

Excellent Summer Workbooks - Keeps Kids Engaged and Ready
Format: Paperback
These workbooks have been an absolute lifesaver for keeping my kids on track over the summer! I was looking for a resource that would help them retain what they learned and prepare for the next school year without feeling like a chore, and these deliver perfectly.
What I particularly love is how well **organized they are by days**. This structure eliminates any guesswork and makes it incredibly easy to assign manageable chunks of work each day, which helps to **keep my kids consistently on track**. There's no overwhelm, just steady progress.
The content is engaging, and it genuinely seems to reinforce key concepts in a fun way. We've had **absolutely no complaints** from the kids, which is a huge win for any summer learning material! I highly recommend these workbooks for any parent looking for a structured and effective way to bridge the academic gap during the summer break.
