• Operates 2 or 3 lamps on either side of the vehicle.
• Includes mounting bracket for secure installation.
• Supports hazard warning function when used with switch 5227.

Compliance and Safety

Confirm indicator and hazard operation after fitting, then check that the trailer pilot lamp responds correctly. Also inspect terminal tightness and earth quality, because poor connections can cause unstable flash behaviour or false fault indications.

Trailer Applications
