Common Auto Electrical Acronyms

The auto electrical industry is flooded with acronyms which can be confusing at best. In order to improve communication across the board between sparky and client, we thought it a good idea to highlight some of these acronyms. Keep in mind that some of these might be rarer than others, but we never shy away from covering all bases at Bashi’s Auto Electrical. We have also included some more…. informal terms that one might hear around the shop should you be waiting for us to get you back on the road.

Auto Electrical Acronyms

ECE Regulations

This stands for the Economic Commission for Europe who aim to create a uniform system of regulations relating to vehicle design.

RoHS Compliant

Restriction of Certain Hazardous Substances is the certification that states that the proportion of hazardous or difficult to dispose of substances in a piece of electronic equipment is limited.

E Marking On Headlights

This is part of the ECE regulations and is required on all headlights to show they conform to performance standards. The number denotes which country approved it with Germany (E1) having the highest standards.


The Australian Design Rules are our own national standards for vehicle safety, anti-theft and emissions. They cover issues such as lighting, structures, noise, exhaust emissions and occupant protection.

CE Compliant

This stands for “conformité européenne” which is French for European Conformity and is one you might have seen before. It is a declaration by the manufacturer that the product in question meets all relevant provisions in relation to health, safety, and environmental protection standards.


Radio Frequency Interference and Electromagnetic Interference are used to describe “noise” in RF systems. Noise is generally regarded as any RF energy that is not the desired signal with EMI being random noise and RFI meaning noise broadcast at specific frequencies.
