Visibility Essentials

LED Brightness

Radar speed signs need to be bright so drivers can see them. Signs with 5000 to 7000 nits are easy to see, even in sunlight. New radar speed signs can change how bright they are by themselves. They get brighter during the day and dimmer at night. This stops the lights from hurting drivers’ eyes. Anti-glare coatings help by cutting down on shiny reflections. This makes the numbers easy to read in any light. Picking radar speed signs with these features helps keep roads safe. Drivers can see their speed and slow down if needed.

Tip: Pick radar speed signs that can change brightness and have anti-glare coatings. These features help drivers see the signs in any weather or light.

Digit Size

The size of the numbers on radar speed signs is important. Bigger numbers are easier to see from far away. This gives drivers more time to slow down. Here are some tips for picking the right size:

• Use 15-inch numbers in cities with slow traffic. Drivers can see them from 400 feet away.

• Use 18-inch numbers on highways. Drivers can see them from over 600 feet away.

• Bigger numbers help in bad weather or low light. They make it easier for drivers to react.

• Rules like MUTCD say how big the numbers should be for each road.

• Where you put the sign and how high it is also matters. In cities, put them 5-7 feet high. On highways, put them 7-10 feet high.

• Bigger numbers cost more and use more power. Think about your budget and what you need.

Choosing the right number size helps drivers see the signs and keeps roads safe.

Viewing Angle

You want as many drivers as possible to see the radar speed sign. The viewing angle tells you how well drivers can see the sign from different spots. Kalitec says a 55-degree angle works best. This lets drivers see the sign from close up or far away. A wide viewing angle means drivers in all lanes can see their speed. This helps keep everyone safe and following the rules.

Contrast and Anti-Glare

Good contrast and anti-glare help drivers see the signs in bright sun or bad weather. Anti-glare glass with less than 5% shine stops sunlight from making the sign hard to read. Some signs use HDR10+ to make the numbers stand out, even in strong sun. Radar speed signs like R1500 and R1800 use full anti-glare displays. They have the best contrast and can be seen from far away. Black backgrounds help drivers see the numbers in rain or snow. Signs with sensors can change brightness when the weather changes. All these features make sure drivers can always see the signs. This helps keep roads safe in any weather.

Note: Anti-glare and high-contrast features help in all weather. They make radar speed signs easy to see in rain, snow, or fog. This keeps roads safer all year.

LED Radar Speed Signs Placement

Line-of-Sight

Radar speed signs should be easy for drivers to see. Put them on straight roads, not right after curves. This gives drivers time to notice the sign and slow down. Make sure there are at least 100 meters of clear road before the sign. Drivers can spot the display early and change their speed. Aim the radar beam at the lane you want to check. This helps the sign work for all cars. Adjustable brackets let you change the angle for better viewing. Test the sign’s spot during busy times to find the best place. This helps you avoid missing cars.

Tip: Use temporary mounts to line up radar speed signs before you install them for good. This helps you pick the best spot and makes sure all drivers can see the sign.

Mounting Height

How high you put radar speed signs matters a lot. In busy areas, mount signs 8 to 12 feet above the ground. This keeps the display above parked cars and other vehicles. On highways or roads with big trucks, you may need to go up to 20 feet. The right height lets all drivers see the sign, even those in tall vehicles. Adjustable systems help you change the height for different roads. Following these tips helps drivers see the sign and gives them more time to slow down.

Avoiding Obstructions

Things like trees, parked cars, other signs, and buildings can block radar speed signs. Bad weather like fog, rain, or snow also makes signs hard to see. Always look for things that could hide the sign from drivers. Put radar speed signs away from other traffic equipment to keep things clear. For solar-powered signs, pick a spot with lots of sunlight. In busy areas, test the spot during rush hour to see if big vehicles block the sign. Strobe lights can help drivers see the sign in bad weather. By picking a good spot and moving things out of the way, radar speed signs work better to slow down traffic.

Weather and Durability
