Why replace your factory ARB signals?

Many owners find the factory ARB indicator lamps to be a weak point—they are prone to moisture ingress, use outdated bulbs that melt the housing, cant offer a modern alternative and are often redundant "extras". The Beacon+ system replaces these disposable units with a aluminum and glass-fiber reinforced housing that mounts modern 3 x 2 pod lights in their place and points your light straight where you need it.

How to Choose the Correct Replacement Kit

The Aptomo Beacon+ is the high-performance alternative to standard ARB factory signal assemblies. Use the guide below to replace your unreliable or redundant halogen/LED units with a serviceable pod-mount system."

1. Identify the Lamp You’re Replacing

ARB has used only a few signal lamp families across their entire bumper lineup—but each bumper applies those lamps differently.

Because of this, you must start by confirming which OE lamp your bumper uses.

1. Rectangular Signal (Legacy ARB Style)

The classic rectangular signal is the most common lamp used across ARB’s older and mid-generation "Deluxe" bumpers. Its borrowed from a MK1 VW Jetta part number 3500080

These bumpers typically require the Rectangular Beacon+ Kit, available in multiple angle-compensation options to match your bumper’s rake.

Common fitments include 100 series and older Land Cruisers, Land Rovers, Tacoma/4Runner and pickup platforms.

2. Capsule / Oval Signal

The capsule-shaped lamp is ARB’s newer compact signal found on many of their later model "Summit" and "Deluxe" bumpers. Its rounded oval profile and clear led lamp are defining features. Part number 6821287

For these bumpers you’ll want the Capsule Beacon+ Kit, designed to drop in cleanly while maintaining proper aim with your chosen angle compensation.

Common fitments include newer 4Runner/Tacoma, newer Land Cruiser and Domestic platforms

3. Integrated Fog + Signal Housing (In Development)

Some of ARB’s latest bumpers combine the turn signal and fog light into one integrated assembly. These require a specialized replacement that preserves both functions in a single housing. Our Integrated Fog/Signal Beacon+ Kit is currently in development.

Customers running these bumpers can sign up for updates as this kit approaches release.

2. Understand Your Bumper’s “Rake” (Mounting Angle) and How to Measure.

Each ARB bumper sits differently relative to the vehicle’s front end.

This angle is referred to as the rake—the angle of the lamp mounting surface.

  • Some bumpers (like the Land Rover Defender) have almost no rake at all.
  • Others (like the 5th gen 4Runner) have significant rake, tilting the lamp outward

Because of this variation, every Beacon+ kit includes multiple installation options so you can tune the light direction based on your bumper’s angle and your lighting goals.

An up to date list of fitments by application is not yet compiled due to ARB's extensive catalog. It is important that each user first measures the bumpers rake angle before proceeding to the next step. See the image below for guidance, this can be found with either an angle finder, protractor or by using a little trigonometry.

3. Choose Your Beam Direction (Forward or Outward)

Each kit includes a few mounting configurations that change the light’s aim.

If you run flood or fog optics:

  • A slight outward angle gives better spread and noticeably improves side visibility.
  • This is recommended for wide-beam lamps.

If you run spot optics:

  • Aim the light as straight ahead as possible.
  • Spot beams benefit from maximum forward projection.

4. Choose the Correct Angle Compensation (0°, 10°, 15°, and 20°+ Options)

Each kit is labeled by how much angle it corrects—not how much angle your bumper has.

Your measured bumper rake tells you how much correction you need; the kit’s rating tells you how much correction is available.

  • 0° → no correction
  • 10° → compensates for 10° of bumper rake
  • 15° → compensates for 15° of bumper rake
  • 20°+ → extended correction for high-rake bumpers (varies by kit and may require custom configurations)

Note: there may not be all of these options available at this time, complete the contact form if there is something specific you are looking for.

How to Use These Values

You compare your bumper’s rake to the kit’s correction:

  • If the bumper rake is equal to or less than the kit’s rating, the lamp can be aimed directly forward (or slightly outward, depending on your preference).
  • If the bumper rake is greater than the available compensation, the remaining angle will cause the lamps to point outward by the difference.

Example: Bumper Exceeds Available Compensation

If your bumper measures 30°, and the kit you select provides 20° of correction:

  • Bumper rake: 30°
  • Kit compensation: 20°
  • Remaining angle: 10°
  • Final lamp aim: about 10° outward

This does not prevent installation—it simply sets the lamps outward by the uncorrected amount.

20°+ Option (High-Rake Bumpers)

The 20°+ options cover high-angle applications, but physical clearance inside the bumper pocket becomes a factor. At very high angles, light housings may contact the bumper pocket and have deeper inset measurements.

If you measure beyond the standard range or need a precise correction, a custom-angle kit can be made. Note that some applications do not allow for the lamps to sit level with the ground by the nature of the cutouts, in this case a flood beam may be the best option.
