This one marks a parking entrance, a listing on a dark street or a detour on an unlit road, and the film works at night with no power. PVC, foam board and aluminum signs are on [rigid signs printing](https://www.4over4.com/rigid-signs-printing). For the same board without the film, see [Coroplast](https://www.4over4.com/product/coroplast). ### How Bright Does It Look at Night Two things decide it. The first is angle: the film returns the most light when the headlight is close to straight on, so a sign turned to face oncoming traffic reads far better than one angled off to the side. The second is the artwork: big type, thick strokes and open background give the strongest read after dark. To set up the file, use our [free yard sign templates with bleed, trim and safe zones already set](https://www.4over4.com/guide/free-yard-sign-templates-guide). ### What Size Can a Sign Be, and Can You Print Both Sides You enter the dimensions, from a small directional marker to a lawn-sized sign, and the price follows the size. Print 4/4 when traffic passes on both sides, like a parking lane; the second side adds 50% to the sign price and carries the film too. The panel below lists the ink, grommet, H-stake and proof choices the way the configurator groups them. ### Reflective Coroplast , Configured Your Way 4 option groups, 9 choices, defaults: 4/0: 4 Color Front; Blank Back - 4 groups: 9 total ### How Do You Mount and Display a Reflective Coroplast Sign Grommets give you reinforced holes to zip-tie or screw the sign to a fence, a post or a railing: top two corners for a hanging sign, all four for one that stays put in wind. The wire H-stake slides into the flutes and pushes into soft ground, so a lawn sign or median marker stands on its own. Skip both for a flat panel you lean, tape or bolt. For a rigid metal version with the same film, see [Reflective Aluminum Signs](https://www.4over4.com/product/reflective-aluminum-signs). ### Where Reflective Coroplast Is Used An arrow to an open house, an estate sale or a job site, staked at a turn where a driver has about a second to read it. Entrance and exit markers, visitor parking, delivery bays and after hours instructions, where headlights sweep across the sign every time a vehicle arrives. Access and no parking notices around a work zone that go up for a week or a season, where a light board makes more sense than an aluminum panel that has to be stored. This is a reflective sign, not a regulated traffic control device. Stop signs, speed limits and anything installed in a public right of way have to meet the standard your state or municipality enforces, and this product is not sold as compliant sheeting for that use. ### How Do Reflective Coroplast Signs Compare [Dry Erase Coroplast](https://www.4over4.com/product/dry-erase-coroplast) swaps the reflective film for a wipe-clean surface you update by hand. The panel below sets reflective coroplast beside it and the Standard Coroplast Signs, with the starting price of each. ## Wally makes your sign glow after dark Why a $29 reflective coroplast sign keeps working once the sun goes down. A plain yard sign disappears at night. Reflective coroplast does not. It prints full color on weatherproof 4mm coroplast, then a reflective film catches headlights so drivers still read it after dark. Set any size, add grommets or an H-stake, and Wally ships it in 4 business days from $29. ### The smart pick in coroplast signs Reflective Coroplast beside Coroplast, Dry Erase Coroplast, out of 4 coroplast signs styles - Lowest entry price in the category, $25.00, [Coroplast](https://www.4over4.com/product/coroplast), and 1 more at this price, the cheapest way into the category - Most-reviewed style in the category, 66 reviews, Coroplast, the category's top-reviewed pick at 4.9★ | | Reflective Coroplast | Coroplast | Dry Erase Coroplast | | --- | --- | --- | --- | | Min price | $29.00 | $25.00 | $31.99 | | Paper / stock | 4mm White Coroplast | 4mm White Coroplast | 4mm White Coroplast | | Finish | Reflective Film | · | Dry Erase Lamination | | Default qty | 1 | 1 | 1 | | Turnaround | 4 business days | 3 business days | 4 business days | | Rating | ★ 4.9 (61) | ★ 4.9 (66) | ★ 4.9 (61) | ### What Pairs With Reflective Coroplast Our kit of [8 reflective print products that keep safety signs readable after dark](https://www.4over4.com/kit/reflective-safety-sign-print-set) shows what pairs with it. ### See the Rest of Our Signs The cards below show more of the coroplast family, each with its starting price, and banners and yard signs for the same site are in the full [print product range](https://www.4over4.com/products). ### More From Coroplast Signs - Professional Quality 4 products in the Coroplast Signs - Professional Quality range, including Coroplast, Dry Erase Coroplast, Plastic Coroplast Signs - [Coroplast From $25.00](https://www.4over4.com/product/coroplast) - [Dry Erase Coroplast From $31.99](https://www.4over4.com/product/dry-erase-coroplast) - [Plastic Coroplast Signs From $25.00](https://www.4over4.com/product/plastic-coroplast-signs) [Browse all of Coroplast Signs - Professional Quality](https://www.4over4.com/coroplast-signs-printing) ### Print Your Reflective Coroplast Today At 4OVER4.COM, quality comes first, and it is backed by five guarantees and 25+ years of printing since 1999.
