ECE R65 vs R148: Technical Differences and Application Guide

What's the Difference?

Many buyers confuse ECE R65 and ECE R148 - two UN ECE regulations for vehicle lighting. Here's the simple breakdown:

Purpose:

• ECE R65: Warning and hazard signaling

• ECE R148: Light-signaling devices

Light Color:

• ECE R65: Amber only

• ECE R148: Amber, White, or Red

When Used:

• ECE R65: Hazard situations only

• ECE R148: Normal driving

Typical Products:

• ECE R65: Warning beacons, amber flashers

• ECE R148: Turn signals, reverse lights, marker lights

ECE R65 - Warning Lights

For hazard signaling only. Used on emergency vehicles, tow trucks, wide-load pilots, and construction equipment.

• Amber flashing light

• Activated only in hazard situations

• Must ensure 360 degree visibility

ECE R148 - Light-Signaling Devices

For normal driving functions. Covers turn signals, reverse lights, position lamps, and side markers.

• Technology-neutral, LED-ready

• Standardized flash rates for turn signals

• Required for vehicles over 6 meters, marker lights

Common Applications

Vehicle Type: Emergency vehicle
R65 Needed: Yes, warning beacons
R148 Needed: Yes, turn signals

Vehicle Type: Truck or Trailer
R65 Needed: Yes, amber hazard
R148 Needed: Yes, reverse, markers, turns

Vehicle Type: Wide-load pilot
R65 Needed: Yes, warning light
R148 Needed: Yes, position markers

Vehicle Type: Excavator on road move
R65 Needed: Yes, amber beacon
R148 Needed: Yes, marker lights

Quick Rule of Thumb

Is the light for emergencies or hazards? Choose ECE R65.

Is the light for normal driving, such as turn, backup, or marker? Choose ECE R148.

Many modern products carry both approvals. For example, a reverse light (R148) that doubles as an amber warning light (R65).
