Give your ERA 4 light setup a one-of-a-kind look — printed vinyl overlays in dozens of colors and designs.
⚠️ THIS LISTING IS FOR THE FULL-SIZE FLEX ERA 4 (KC cover part #5325)
KC makes two different square Era 4 lights, and the covers are not interchangeable. The Era 4 Mini is the newer, smaller light; the Era 4 is the original full-size light. Check the part number on your KC cover (or the light itself) against the table below — an Era 4 Mini overlay will not fit an Era 4 cover, and an Era 4 overlay will not fit a Mini cover.

Custom Covers Without the WorkKC HiLiTES publishes a PDF template for making your own custom FLEX ERA 4 light covers — but not everyone has the time, the cutter, or the patience. We do the work for you: precision-printed vinyl overlays that drop right onto your covers and transform the look of your light setup. Used over amber or clear covers, the overlays appear backlit when your lights are on, so your rig stands out day or night. |

Dozens of Colors & DesignsPick from 37+ options — solids, outlines, camo patterns, gradients, and "The Original" styles. Whether you want a subtle Cool Gray, a loud Cyber Orange, or a Heritage Blue throwback, there's a look to match your build. Don't see the color you want? If you spot a shade elsewhere on our site, just reach out and we'll see what we can do. |
See It Lit UpWatch how the overlays come alive when the ERA 4 lamps fire up. The printed design glows through amber and clear covers for a custom, backlit finish that looks factory-clean. |
Install WalkthroughA wet install gives the best results. Watch our step-by-step video, then follow the recommended process and tools below. With a little heat and patience on the curves, you'll get a clean, bubble-free finish. |
Prefer a Dry Install? Watch This FirstThis dry install video shows the newer, smaller Flex Era 4 Mini cover (part #5220). The technique is the same on the full-size Era 4 cover (part #5325): clean the cover, peel, align, and squeegee flat from the center out. The dry method is quicker, but it gives you one shot at placement, so it is best if you have installed vinyl before. New to vinyl? Stick with the wet install above. |
Ideal temp is 75–85°F — if it's warm, work in the shade; if it's cool, warm the surface. Clean the cover, spray it and the overlay with StickerFab Application Fluid (or 1 drop of dish soap per cup of water) as you peel it off the backing. The fluid lets you align it perfectly and keeps it from sticking to itself. Once aligned, squeegee out the fluid and bubbles, then use heat and your fingers to work the curved areas.
Recommended tools: quick detailer, microfiber, application fluid, a felt-tip squeegee, and a heat gun or hairdryer. Grab the 3-item install kit to get everything in one shot.

Return policy

Depends on the part. Some are straightforward DIY, others are body shop or specialist work. Each product page indicates the recommended install path. If you're unsure, message us with your build details and we'll give you a real assessment.
Live chat and email — typical response time is a few business hours, and you can reach out anytime. Chat with us on the site or email support@k2-industries.com. We resolve issues directly far faster than going through your bank or card processor.
Find your next upgrade
Every part listing shows compatible years, models, and trims. But here's the thing—trim packages and factory options can be confusing. If you're not 100% certain, text us at 772-277-2495 with your VIN or photos of your car. We'll verify fitment before you order so you're not stuck with an $800 part that doesn't fit. We've done this for 30,000+ builds. We've seen every weird trim combo and factory option. Takes us 2 minutes to verify, saves you weeks of headaches.
We handle it. You don't fight with freight companies or file claims. Text us photos within 48 hours of delivery. If it's damaged or wrong, we ship a replacement immediately. You're not waiting 6 weeks for a freight claim to process. We eat the cost, not you. This is why we package everything like it's going to war. But if something slips through, we fix it ASAP. No forms, no back-and-forth, no "file a claim and wait." Just text us and we handle it.
Depends on the part. Emblems, front lips, some spoilers, bolt-on, DIY-friendly, you can do it in your driveway with basic tools. Full bumpers, hoods, wide-body kits, possible for experienced DIYers but most people take them to a shop for paint and install. Check the product description for installation difficulty. If you're unsure, text us. We'll be honest about whether you can handle it or if you should take it to a pro. We'd rather you know upfront than get frustrated halfway through.

Yes. Affirm and Shop Pay available at checkout for orders over $50. Split payments over 3-12 months depending on order size. No hard credit check to see your options. Most people use this for big-ticket items like body kits, suspension setups, or wheel/tire packages. Rates vary based on credit. You see the monthly payment before you commit. Makes it easier to build now instead of waiting months to save up.
Text 772-277-2495. We don't disappear after you buy. Fitment questions, installation issues, "does this bolt go here" questions... we'll walk you through it. We've installed these parts ourselves or helped hundreds of people install them. You're not getting transferred to a call center in the Philippines. You're texting someone who's actually installed your part before. If we can't help remotely, we'll recommend a local shop that knows these parts.
eBay and Amazon sellers don't answer fitment questions. They don't verify your VIN before shipping. They don't handle freight damage claims for you. If something goes wrong, you're filing disputes and waiting weeks. We're builders selling to builders. We verify fitment before you order. We handle damage claims same-day. We answer texts in minutes. We're not the cheapest, but you're not gambling $800 on whether a part fits. You're paying for support, verification, and someone who cares if your build goes sideways.
