My Van Electrical Loads: Exterior Lights, Stereo and Cameras

The Devices the Electrical System Serves

My electrical equipment includes San-Young LED work lights, a Nilight 71017C-A curved light bar, a PLZ stereo and a Ciascy four-channel dash-camera system.

Their operating power and running time contribute to the van’s daily energy use.

San-Young LED Work Lights

San-Young LED Work Lights

These SanYoung LED pods provide auxiliary illumination around a van. Their mounting brackets attach the lamp housings to a supporting surface.

Nilight 71017C-A Curved LED Light Bar

This curved LED light bar combines spot and flood illumination in a wide auxiliary fixture. Its long curved housing forms a separate light assembly from the smaller work-light pods.

Exterior Work Lights and the Light Bar

My exterior lighting includes compact San-Young work-light pods and a separate Nilight curved light bar.

Stereo and Camera Equipment

The PLZ stereo handles audio and touchscreen functions. The separate Ciascy system displays camera views on its own monitor.

For the stereo, a marketed audio-output figure should not be treated as the device's measured continuous draw from the battery. Measuring the device in use answers that separate question.

Video Connections

Tengchi RCA-to-HDMI Converter

This powered adapter converts composite RCA video and stereo audio into HDMI. The illustrated version has red, white and yellow RCA input leads and an HDMI output lead.

The video cables I used include red/white/yellow RCA and an HDMI-to-Mini-HDMI cable, as labeled in the drawings. Red and white RCA carry audio; yellow carries composite video.

Switching the Loads

I used a Nilight six-gang DC switch panel for branch controls. The distribution guide covers that equipment alongside bus bars, fuse holders and wiring.

Label a load record with both the device and circuit function, such as lighting or camera equipment.

Turning the Device List Into an Energy Budget

Record each device’s operating watts and time in use. Watts multiplied by hours give watt-hours. For current measurements, retain voltage and the measurement point with the reading.

A low-power device left running for hours can use more energy than a powerful device used briefly. The hub’s worked example shows this calculation.

The battery guide connects that daily demand with stored energy and runtime.
