Hi everyone i have a '99 freelander and i've put a set of lights on my roof i mocked up the wiring diagram and now i've lost my buzzer when i turn the lights on ??.
and my NSR fog light is staying on when key goes into the ignition ??

Somebody has said that the buzzer is controlled inside the CCU on the back of the fuse box,
can i just change the CCU for another CCU from another L series FL or does the original one control central locking and electric windows etc ??
or are they controlled by a fuse or relay
HELP REQUIRED

By buzzer. I assume you are talking about the lights on alarm.
Have you disconnected your new lights to see if the alarm returns.

It is incorporated into the CCU, on the rear of the fuse box.

It's not straightforward to simply change the CCU, as it controls the remote locking too.

You need to identify what is causing your issue before delving deaper and replacing parts.
