A sign is only useful if people can read it when they need to. After dark, or in poor light, a plain painted or printed sign can disappear. Reflective materials are designed to help signs stay visible when headlights fall on them. This guide explains the basics in plain language and how to choose.
What “reflective” means
A reflective sign face is made with a material that sends light from a vehicle’s headlights back towards the driver. When lit at night, the sign appears bright. In daylight, it looks like a normal coloured sign. This is different from glow-in-the-dark signs, which store light and glow in darkness without a light source shining on them. We cover those separately below.
Reflective versus non-reflective
Non-reflective signs are cheaper and are often perfectly adequate indoors, in well-lit yards, or where signs are only used in daylight. Reflective signs cost more but are the sensible choice where:
- Vehicles approach the sign at night
- Street lighting is poor or absent
- The sign marks a hazard or a stop point
- The sign is on a road that is used around the clock
There are different grades of reflective material, and different roads can call for different grades. We do not state which grade a given road requires. For public roads, confirm the requirement with the relevant road authority or a traffic engineer. For workplace signs, ask your health-and-safety officer.
Reflective options in our range
Reflective Chromadek
Chromadek is a coated steel sheet. Reflective Chromadek signs combine a steel substrate with a reflective face, giving a rigid, durable sign suited to permanent outdoor installation. See choosing sign materials for how steel compares with other substrates.
Aluminium substrate
Aluminium is a light, corrosion-resistant base that can carry a reflective face. It is a good choice where weight matters or where rust is a concern.
High-visibility road signs
Our high-visibility road signs category groups signs designed to stand out more strongly. Check each product page for the material and finish.
Reflective safety signs
For workplace use, the reflective safety signs category covers mandatory, prohibition and warning messages with a reflective face.
Glow-in-the-dark is not the same thing
Photoluminescent (glow-in-the-dark) signs absorb light and release it slowly. They are useful for fire equipment and escape route signs inside buildings, where power may fail. They do not replace a reflective sign for traffic. We offer them in ABS and Chromadek, and you will find them in glow-in-the-dark signs.
How to decide
1. Think about who will see the sign and when
If drivers will pass it in the dark, choose reflective. If it is an indoor sign for staff, reflective may be unnecessary.
2. Think about the hazard
A sign that warns of a hazard or controls traffic deserves a face that works at night. The cost difference is small compared with the consequence of a missed sign.
3. Consider the environment
Dust, grime, salt air and sun all affect how a sign performs over time. Keep reflective faces clean. Our caring for and replacing signs guide has practical tips.
4. Match the approach across a site
Mixing reflective and non-reflective signs of the same type can look inconsistent after dark. Where a set of signs forms a system, such as an estate’s stop and speed signs, use the same finish throughout.
Questions to ask before ordering
- Will vehicles approach this sign after dark?
- Has the road authority or traffic engineer specified a reflective grade for this location?
- Is the substrate suited to the environment?
- Do I want the whole set to match?
