In this video, you will see how to make a small and inexpensive modification even on an older vehicle like a 1994 Ford Transit; connect a sound buzzer to the sidelights, so if you forget them on, you will receive a warning and avoid draining the battery.

Follow the fuse diagram available, connecting the wiper fuse and the sidelights fuse.

This way, there is no need to dismantle half the dashboard, but connect the positive and negative together with a small buzzer that costs very little at any parts shop and fits easily into the fuse box. Alternatively, you can also take the negative from the back of the door switch, so that when the door opens and the light is on, it sounds, but this requires removing part of the dashboard.
