Electrical Check Before Every Trip

Before hitting the road, always take 2 minutes to check your trailer’s electrical system. A small issue like a non-working taillight can lead to big problems — from fines to dangerous situations on the road.

What to Check:

1. Light Functions:

Brake lights
Turn signals (left and right)
Running lights and reflectors
Reverse lights (if equipped)

Tip: Use a friend or reflective surface to confirm all lights are working.

2. Wiring Condition

Look for cracks, exposed wires, or corrosion on connectors.
Make sure wires aren’t dragging or loosely attached to the trailer frame.
Check the 7-pin or 4-pin plug for clean, solid contact.

Tip: If you see frayed cables — tape isn’t a fix. Replace or professionally repair before towing.

3. Battery (if equipped)

If your trailer has an onboard battery (e.g., for brakes or internal lighting), check the voltage level and charge. A dead battery can disable electric brake systems.
