Australian fitment and buying guide · Reviewed 17 October 2026
A GWM Cannon light bar purchase starts with the mounting application. Match the ute and the bracket first, then check the lamp’s complete dimensions, beam performance and electrical requirements.
This guide separates the manufacturer’s listed applications from the measurements needed for an aftermarket installation. It covers Cannon and Cannon Alpha owners planning grille, bar or roof positions in Australia.
Which light bar fits Cannon?
There is a verified starting point for size: GWM Australia lists a 20-inch LED light bar for each model family, with different part numbers and specified genuine mounting accessories.
On a phone, swipe the application table sideways.
| Model family | Listed lamp | Listed mounting application |
|---|---|---|
| Cannon | 20-inch LED light bar, AGP0604010A. | Specified genuine GWM bull bar, style bar or nudge bar. |
| Cannon Alpha | 20-inch LED light bar, AGP1604010A. | Specified genuine Cannon Alpha bull bar or nudge bar. |
Sources: GWM Cannon accessories and GWM Cannon Alpha accessories. Confirm applicability to your exact vehicle and bar assembly before ordering.
Cannon variant fitment differences
Identify whether the vehicle is a Cannon or Cannon Alpha, then record the build date, trim, powertrain and fitted front-end accessories. Keep photos of the actual grille and headlamp area with the supplier’s application check.
Check a bracket listing against that complete description. A broad “fits GWM Cannon” label does not establish interchangeable mounting points or clearance across different front-end arrangements.
For a vehicle with an aftermarket bull bar or nudge bar, include the bar manufacturer, model and mounting drawing. Changing the bar can change the light installation even when the ute itself stays the same.
Bar types: single row vs dual
Single row
Compare the actual housing height and depth when space is tight. A slimmer candidate can be easier to package, but it still needs bracket, connector and adjustment space.
Dual row
Check the complete housing and mounting dimensions. Row count alone does not establish useful beam distance, spread, input current or compatibility with the vehicle.
A nominal inch size is a shopping label. It may describe a different measurement from the overall width including end mounts; use the dimension drawing for the exact lamp.
For country-road driving, compare beam distance and spread using measurements taken under comparable conditions. For low-speed work, decide whether a separate work-light arrangement better matches the task. A spot, flood or combo label alone is an incomplete comparison.
Ask for the actual electrical input requirements alongside beam data. A large lumen claim does not tell you whether the lamp fits, where the light lands or which harness is suitable.
Mounting positions that work
Behind the grille
Check the lamp’s illuminated face and its entire housing, including mounts and connectors. Assess the opening, cooling airflow, nearby components, sensors and the adjustment needed to aim the beam.
Use the vehicle, lamp and mounting-kit instructions to establish required clearances. There is no verified universal air-gap figure in this guide; an arbitrary gap cannot prove cooling or fitment on every variant.
On a nudge bar or bull bar
Use the mounting points or clamps specified for that exact bar. Check tube diameter if clamps are proposed, rather than assuming all bars accept the same clamp size.
Consider the lamp and bracket’s effect on projections, number-plate visibility, factory lights and sensors. Our Cannon bull bar guide covers the related buying decision.
On a roof platform or rack
Check the platform, attachment hardware, wiring route, vehicle height and reflections from the bonnet. Physical room for a longer bar does not establish permission to use it as a driving lamp.
A roof platform’s integrated LEDs also need their own lamp specifications and installation check. Treat the roof structure, mounting and electrical system as separate parts of the decision.
Swipe sideways to view the measuring checklist.
| Check | Record for the actual installation |
|---|---|
| Lamp envelope | Overall width, height and depth in mm, including end mounts. |
| Bracket arrangement | Attachment pattern, adjustment range and specified fasteners. |
| Connector space | Connector projection, cable exit and required bend space. |
| Vehicle clearance | Opening, nearby components and manufacturer-required cooling space. |
| Aiming and visibility | Beam adjustment, driver view, plate, sensors and factory-lamp clearance. |
| Operating requirements | Input current, approved harness and control interface for the exact lamp and vehicle. |
Wiring the Cannon light bar
Start with the lamp harness instructions and vehicle-specific electrical information. Confirm how the installation receives a valid high-beam signal and how the driver disables the additional driving lamps.
Road-use control concept: high-beam permission + accessory enable → lamp operation through a suitable protected power circuit.
This describes the intended control behaviour, rather than a pinout or instruction to splice a particular wire.
A positive high-beam tap is not a universal instruction. The installer needs to establish the actual signal and the compatible interface on your vehicle before selecting a connection method.
Likewise, a console switch marked “12V-1” does not establish its circuit rating or wiring function. Check the switch documentation, harness interface and lamp load; do not infer them from a label or an owner video.
Commission the high-beam control
NSW VSI 64 requires automatic switch-off with high beam and separate disabling while high beam remains on. Have the installer check these states:
- High beam off: the driving light remains off.
- High beam on, accessory disabled: the vehicle’s high beam works without the additional lamp.
- High beam on, accessory enabled: the lamp operates as intended.
- Headlights dipped: the additional lamp turns off automatically.
Verify the supplied fuse, relay or controller, wiring and connectors against the lamp and harness instructions. Avoid choosing fuse or cable ratings from a generic Cannon example.
Australian road-use checks
Check both fitting and use for the state where the vehicle will be driven. Driving lamps, work lights and replacement headlamps have different functions; an off-road label or a protective cover does not establish a compliant driving-lamp installation.
New South Wales
NSW VSI 64 sets a four-lamp maximum, white output and placement requirements. Elevated lamps are discouraged because of glare; the full fitting and use conditions still apply.
South Australia
SA’s driving-light guidance also lists a four-light maximum, white output and main-beam-only operation, with positioning and projection conditions.
The page permits conditional roof fitment where it avoids driver glare. Read the complete position requirements for the proposed arrangement.
These are state-specific examples, not approval for a particular lamp or installation. Confirm the applicable rules elsewhere, aim the lamps correctly and avoid dazzling other road users.
Fitment checklist before buying
- Identify the ute: model family, build date, trim, powertrain and current front-end accessories.
- Choose the position: check its physical and road-use requirements before choosing a nominal lamp length.
- Match the actual dimensions: housing, brackets, connectors and adjustment space.
- Compare useful light: beam information and input requirements under stated test conditions.
- Confirm the electrical plan: vehicle interface, suitable harness and high-beam control.
- Get a complete quote: lamp, mounts, harness/interface, fitting and applicable charges, with the currency identified.
For several front-end accessories fitted together, include their locations and cable routes in one plan. See our Cannon snorkel guide for that separate accessory decision.
Fitment check
The verified applications above relate to the manufacturer’s named lamp and genuine mounting accessories. This article does not certify a blanket year range or a universal behind-grille bracket.
For an aftermarket fitment enquiry, send the exact vehicle, mounting-bar model, lamp drawing, proposed bracket and clear photos of the intended location. Include the registration state if road-use driving lamps are planned.
GWM Cannon light bar FAQ
Will a 22-inch light bar fit behind my GWM Cannon grille?
The inch label alone cannot confirm fit. Compare the complete housing, brackets, connector and adjustment space with your actual grille location. Obtain compatibility for the exact vehicle and bracket kit; do not apply one installation example to every Cannon or Cannon Alpha.
What light-bar size does GWM list for the Cannon?
GWM Australia lists a 20-inch Cannon light bar, part AGP0604010A, for specified genuine bar accessories. The Cannon Alpha listing uses a different part, AGP1604010A, also described as 20-inch. Neither listing establishes universal behind-grille fitment.
Are Cannon and Cannon Alpha light-bar brackets interchangeable?
Do not assume they are. Match the exact vehicle, bar assembly and mounting-kit application. Similar lamp length or the Cannon name does not establish the same attachment points, available space or electrical interface.
Is a dual-row light bar automatically better than a single row?
Compare actual housing dimensions, beam data, input current and intended use. Row count alone does not establish useful road illumination or fit. Use comparable beam measurements and the complete installation envelope when choosing.
Can I connect a light bar to the Cannon 12V-1 switch?
The retained video shows one owner’s 2025 installation example. Before using that approach, have the actual switch circuit, current rating, control interface and lamp harness checked against your vehicle documentation. A switch label is not a wiring diagram or proof that the circuit can power the lamp.
Should the light bar turn off when I dip the headlights?
NSW VSI 64 requires automatic switch-off with high beam, plus separate disabling while high beam remains on. Verify that behaviour during commissioning and check your jurisdiction’s requirements.
Can I use a roof-mounted light bar on Australian roads?
Check the state rules and the completed installation. NSW discourages elevated driving lamps because of glare; South Australia lists conditional roof fitment. Physical mounting space alone does not establish legal road use.
Does covering a light bar make an otherwise unsuitable installation compliant?
Do not treat a cover as proof of compliance. Check the lamp type, mounting position, visibility, projections, wiring and use against the rules that apply to the installation. A cover does not establish those properties.
Recommended parts: match the part to its role
Choose the light bar, compatible mounts and vehicle interface as a complete installation. If you are also building a roof-based touring setup, the platform below is a separate accessory to assess.
For other vehicle-specific equipment, browse the GWM Cannon accessories collection. Send your fitment details if the proposed roof arrangement needs checking.
