Daytime running lights

Daytime running lights (DRL) are purpose specific white lights fitted to the front of vehicles. Their function is to make the vehicle more conspicuous against its background at times when headlights are not typically used. They are increasingly being fitted to premium brands such as Audi and HSV, however they have been used by Volvo since the 1970’s.

Various studies suggest DRLs may offer road safety benefits. As a result the European Union introduced a requirement that all new passenger cars and small delivery vans sold in participating European countries from February 7, 2011 be equipped with DRLs. Trucks and buses will be required to comply from August 2012.   

The design and operation of DRLs is covered by Australia Design Rule for Road Vehicles 76/00, however in Australia their fitment is optional. This may change if the European regulation is adopted by Australia.

Daytime running lights must switch on automatically when the vehicle starts and switch off automatically when the front fog lights or headlights are switched on.

It has been suggested that driving with low beam headlights lit during the day offers similar safety benefits, however there is concern from certain groups that this could make motorcycles less conspicuous. Additionally, the use of high power consumption lights, such as headlights, will result in a small increase in fuel consumption and therefore increased exhaust emissions. The current generation of Light Emitting Diode DRLs have very low power consumption and could not be mistaken for a motorcycle headlight.

A number of automotive electrical equipment manufacturers offer DRL kits for retrofitting. Look for kits that comply with ADR 76/00 or ECE R87.
