Choosing a headlight globe

Start with the code, then the voltage. An H4 is a twin-filament high/low globe and the most common fitment on older 4x4s, while H7, H11, HB3 and HB4 are single-filament globes used in pairs on later vehicles. HB3A and HB4A are the same globes with a different base, so the code on the old globe decides. Every globe here lists 12V or 24V in the name, and the 24V halogen range covers the truck fitments.

Then pick the grade. Halogen upgrade globes are sold by output over a standard globe. Narva's Plus 30, Plus 50 and Plus 60 ranges put more light on the road at the same wattage, which keeps the wiring and lens legal, and the Long Life and Everlife ranges trade some output for filament life. Blue-coated globes such as Arctic Plus 50 give a whiter light at the same output rating. A blue globe with no plus rating gives less light on the road, not more.

LED, HID and signal globes

  • LED headlight conversion globes in H4, H7, H11, HB3 and HB4 are rated 9 to 16V or 12/24V and up to 5,000 lumens a pair. A halogen headlamp housing was approved with a halogen globe, so an LED conversion in that housing is not ADR compliant for road use. For a legal LED upgrade see the headlamp inserts under headlight replacements.
  • CANbus vehicles read an LED as a blown globe and flash a warning or hyper-flash the indicators. Use a CANbus-ready LED kit or add a load resistor on that circuit.
  • HID xenon globes are 85V 35W in D1S, D2S and D2R, or 42V D3S, and only fit vehicles with a factory ballast. Match the full D-code, including the R or S, or the beam cut-off will be wrong.
  • Signal globes are coded by base. BA15S is single contact (P21W), BAY15D is double contact with offset pins (P21/5W stop/tail), and BAU15S is the amber indicator base with 150 degree pins. Tungsram Standard and Extra Life incandescent globes are the like-for-like swap, and LED versions run 900 to 1,500 lumens.
  • Interior and plate globes are T10 (W5W) wedge and 31, 36 or 39mm festoon. Measure the festoon tip to tip before ordering.

What else you might need

Headlight replacements: complete lamps and ADR-approved LED inserts where a globe is not enough.

Load resistors: for hyper-flash and globe-failure warnings after an LED swap.

Interior lights: complete LED interior lamps and panels rather than a festoon swap.

Driving lights: for distance that no headlight globe will give you.

Frequently asked questions

Are LED H4 headlight globes ADR approved in Australia?

No. A headlamp is approved as a unit with the globe type it was designed for, so an LED globe in a halogen housing is not ADR compliant for road use. A complete LED headlamp insert with ECE or ADR approval is the compliant path.

What is the difference between HB3 and HB3A?

Same filament and output, different base. HB3A, also sold as 9005XS, sits in the headlamp at a different angle to a standard HB3 (9005), so the two do not interchange. The code is printed on the base of the old globe.

Can I use a 12V globe in a 24V truck?

No. A 12V halogen globe on 24V blows in seconds. Use the 24V globe in the same code, or a 12/24V LED rated for both.

Why do my indicators flash fast after fitting LED globes?

The flasher unit sees the lower current and thinks a globe has blown. Fit a load resistor across each LED indicator globe, or use a CANbus-ready LED kit with the resistor built in.
