| Check | Why it matters |
|---|---|
| Build date and chassis code | Headlights change with facelifts, not just model years |
| Right-hand drive version | A left-hand drive dipped beam points the wrong way |
| Same type as the original | Halogen, projector and LED units are not interchangeable |
| Certification on the listing | Shows the standard the headlight was approved to (E-Mark, SAE / DOT) |
| Aim after fitting | A badly aimed beam dazzles others or limits your view |
| Your state's rules | States and territories enforce roadworthiness, including globe changes |
Which rules apply to headlights?
Vehicles in Australia are built to the Australian Design Rules (ADRs), the national standards for vehicle safety. They are administered under the Road Vehicle Standards Act 2018. Headlamps are covered by ADR 46/00, and the way lights are installed on a vehicle by ADR 13/00. When a vehicle is used on the road, state and territory laws generally require it to comply with the ADRs that applied when it was built, and the states and territories enforce this through registration and roadworthy inspections.
What do E-Mark and SAE / DOT mean?
Australia aligns its vehicle standards with United Nations regulations wherever possible, and is a signatory to the UN 1958 Agreement. An E-Mark on a headlight shows it was approved under those UN regulations; the number after the E identifies the approving country, for example E1 for Germany, E4 for the Netherlands and E13 for Luxembourg. SAE and DOT marks refer to United States standards. Each headlight we list states the certification it carries, and some state none, so you can see exactly what you are buying.
What commonly fails an inspection
Inspectors look at how the light performs, not only at the label. Common problems are a headlight built for a left-hand drive vehicle fitted to a right-hand drive car (the dipped beam points the wrong way), a lens that is cracked, cloudy or letting in water, a headlight that is aimed too high or too low, and a light colour other than white. Rules on fitting LED globes into a headlight designed for halogen globes vary between states and are often stricter, so check before you change globe types.
A checklist before you buy
Match the headlight to your vehicle's build date and chassis code, not just the year. Choose the right-hand drive version for an Australian-delivered vehicle. Replace like with like: halogen with halogen, projector with projector, LED with LED. Check the certification stated on the listing. Replacing both sides keeps the lenses and light output matched.
After fitting: aim and check
Have the headlight aim checked after fitting. A new housing rarely sits at exactly the same angle as the old one, and a poorly aimed dipped beam either dazzles other drivers or lights only the road just ahead. We recommend having headlights fitted by a qualified mechanic or auto electrician.
Where to check for your state
Roadworthy and modification rules are set and enforced by each state and territory. If your vehicle is due for an inspection, or you are unsure whether a headlight is acceptable, ask your state road authority or a licensed vehicle inspection station before you buy.
The short version
An aftermarket headlight can be a perfectly good replacement when it is the right part for your vehicle, carries a recognised certification, matches the original type and is fitted and aimed properly. Check the build date, chassis code and drive side, read the certification on the listing, and confirm with your state authority if an inspection is coming up.
