Motorcycle Indicator Spacing: A Simple Guide
Indicator Spacing and Your Motorcycle!
When you looked at a sleek new motorcycle and wondered why the rear indicators are so far apart or why some aftermarket tail tidies look different from the factory setup. There’s a reason behind it and that is your motorcycle is degsined to comply with the Australian Design Rules.
which are a sets of laws that have strict requirements for indicator spacing which includes both learner-approved motorcycles (LAMS) and full-power bikes.
Understanding The Australian Design Rules (ADR's) and the terms used with in them are key if you are thinking about installing a Tail Tidy or a Fender Eliminator.
Australian law refers to Australian Design Rules (ADR) to set the rules for vehicle lighting. For motorcycles, the relevant rules are:
-
ADR 6/00 – Direction Indicators: Defines the performance and functional requirements for indicator lamps.
-
ADR 19/02 – Installation of Lighting and Light Signalling Devices: Sets the placement and visibility requirements for indicators on motorcycles.
Front Indicators
-
As per current ADR 19/02 requirements: a minimum of 240 mm apart (see ADR 19/02, clauses 6.3.3.2–6.3.3.4)
Front indicators also have to be positioned so they are clearly visible alongside the headlight.
Rear Indicators
-
As per current ADR 19/02 requirements: a minimum of 180 mm apart (see ADR 19/02, clause 6.3.3.5)
This spacing is why some integrated tail lights or tiny aftermarket setups may not comply. If your indicators are too close together, your bike could fail inspection or even be illegal to ride on public roads.
Height Requirements
Indicators also have a height requirement: they must be between 350 mm and 1200 mm above the ground (see ADR 19/02, clauses 6.3.3.2 and 6.3.4).
This ensures visibility to other drivers and is especially important at night or in traffic.
What This Means for Tail Tidies
Fender Elminators and Tail Tidies are popular because they streamline the rear of your bike. But not all tail tidies are made with compliance in mind. If you install one with indicators that are too close together, you could:
-
Fail a vehicle inspection
-
Risk a fine for non-compliant lighting
-
Reduce visibility for other road users
Even if it looks cool, you must ensure your setup still meets the spacing and visibility requirements in ADR 19/02.
Key Takeaways

Australian law requires minimum indicator spacing for L‑class bikes.

Rear indicators must be 180–240 mm apart; front indicators 240–300 mm apart.
