When Do You Need LED Dash Lights?

One advantage of interior dash lights is that you can mount them within the vehicle. This setup allows you to keep them low-profile and out of sight when not in use, creating a discreet way to install LED lights inside your car or truck.

Some applications may be better suited for fully interior-outfitted vehicles, such as an undercover car, to minimize the appearance of exterior emergency lights on the vehicle. Regardless of the reason for using interior lights instead of external light bars, you will find many options available on our website for either application.

Do you need assistance choosing the right deck, dash, or visor lights for your car or truck? Contact our expert team at SpeedTech Lights for more information about the many options that are available. Our service team is ready to help you choose from a wide variety of high-quality warning lights.

Dash Light Bar Sizes: 1, 2, 4, 6, and 8 Head

The number in each model name is the head count, so both the output and the length of the bar scale with it:

• 1-head: A single module for a compact position, such as a rear deck corner or a narrow dash shelf. These are often used in pairs on opposite sides.
• 2-head: The most common dash size for an unmarked vehicle, with enough spread from the front without taking up the whole dash.
• 4-head: A wider bar for primary front or rear warning, where there is room across the dash or deck.
• 6-head: Long enough to work as a traffic advisor, with enough modules to run a directional sweep as well as a warning pattern.
• 8-head: The full-width interior bar, with the most modules for a directional sweep. Tri-color versions are available in this size.

A typical unmarked build runs a 4- or 6-head bar on the dash with a matching bar on the rear deck, so the warning lights can work in both directions.

Striker TIR vs. Virtue MultiColor Linear

Two series cover the range of dash strobe lights:

• Striker Elite (TIR Series): Each LED is focused into a controlled, high-output beam. This gives maximum intensity through the windshield and the best reach at distance, and it also penetrates window tint.
• Virtue Elite (MultiColor Linear Series): Output is spread across a magnifying lens for an even, fully illuminated face. This series includes the MultiColor configurations, such as tri-color and four-color options.

Both series carry Dual Memory, so the bar returns to the last two patterns and colors you selected on the next power cycle. Both are also offered in 1, 2, 4, 6, and 8 head lengths.

Dash, Deck, or Visor: Where to Mount

• Dash: The standard position. The bar sits on top of the dash behind the windshield, giving front warning with nothing visible outside the vehicle.
• Rear deck: The same bar mounted on the parcel shelf for rear warning, which is typically used when the vehicle is stopped in traffic.
• Visor: A flip-down visor light mounts to the sun visor with velcro straps and folds up out of the way when it is not in use. This is useful where dash space is taken by other equipment, and visor light bars cover the split visor options.
• Exterior arrow stick: For traffic direction from outside the vehicle, an arrow stick mounts on the trunk or roof rather than the deck. Browse traffic advisors for those models.

Glare is an important detail to account for in your installation plan. If a bar is mounted too far from the glass, then the lights will reflect back into the cabin at night. So make sure there is no clearance, or pair it with a windshield visor.

MultiColor LED Dash Light Bars: Dual/Tri/Four Color Flashing Configurations

Our MultiColor models of the Virtue® series deck/dash light bars are our newest and most impressive interior warning lights, with a variety of flash patterns that feature both MultiColor flash mode and single-color A or B flash mode. The MultiColor functionality of this bar allows both left and right sides to flash different colors in the same module, giving you true MultiColor flashing functionality. You have a variety of flash patterns in single-color mode A or B, so you can even switch between which color you need to use at that time, giving you the best of both worlds.

With our multicolor models, having clear as your secondary color gives you the extra benefit of the steady burn override Super Take Down® effect. This means when you activate your steady burn override shortcut, your secondary color will go all steady. Therefore, if your secondary color is clear, you get an all-white steady-burn illumination. This is just one of the many features our MultiColor interior warning lights have to offer.

Who Uses Interior Dash Lights

Emergency dash lights serve several roles across public safety and work fleets:

• Unmarked and undercover police vehicles: The main application for police dash lights, since nothing shows outside the vehicle when the lights are switched off.
• Volunteer firefighters and EMS: Warning presence in a personal vehicle, with no permanent exterior hardware to remove.
• Supervisors and detectives: Warning output without the roof profile of a marked unit.
• Security and private patrol: Amber or amber/white bars for vehicles where red and blue are not permitted.
• Tow and roadside assistance: A rear deck bar adds warning on the back of a truck that already carries an exterior bar.

Frequently Asked Questions About LED Dash Lights

What are LED dash lights?

LED dash lights, also called LED dashboard warning lights, are interior emergency warning light bars that mount on the dashboard or rear deck of a vehicle, behind the glass. These are different from the warning indicators on your instrument cluster. A dash light bar gives front or rear warning output while keeping the exterior of the vehicle clean, which is why they are standard on unmarked and undercover builds.

How many heads do I need on a dash light bar?

The head count you need depends on the mounting width and how much output the position has to carry. A 1- or 2-head bar suits a compact dash position or a rear-deck corner. A 4-head bar covers primary front or rear warning. The 6- and 8-head bars are long enough to run a directional traffic advisor sweep, as well as a warning pattern.

What is the difference between Striker and Virtue dash lights?

Striker Elite bars use TIR optics, which focus each LED into a controlled high-output beam for maximum intensity through the windshield. Virtue Elite bars use MultiColor Linear optics, which spread output across a magnifying lens for an even, fully illuminated face. They also come in multi-color configurations. Both are offered in the same head counts with Dual Memory.

Can dash lights be used as a traffic advisor?

Yes, the 6- and 8-head bars work as traffic advisors. They carry enough separate modules to run a left, right, or split directional sweep from inside the vehicle. The shorter 1-, 2-, and 4-head bars are warning bars rather than directional units, because a sweep needs more modules to read clearly from a distance.

Are interior dash lights as bright as an exterior light bar?

Interior bars use the same LED and optic technology as exterior units, so output is comparable head for head. The difference is that the light passes through the windshield, which can affect overall intensity, and the mounting position limits how wide the spread can be. For a marked vehicle working traffic at speed, an exterior bar still gives better all-round coverage.

Can dash lights flash more than two colors?

Yes, the MultiColor Virtue bars go beyond two colors. Dual-color is standard across the range, and tri-color and four-color configurations are available, with the left and right sides able to flash different colors from the same module. Single-color A or B mode lets you switch to one color when the situation calls for it.
