Will Trailer Battery Cause 12 Volt Accessory Circuit LED of Hopkins Connector # HM48503 To Light Up
Question:
I recently purchased the Hopkins 7 way connector #48503 and installed it on my travel trailer. The only issue I am having is that the aux indicator light is always illuminated regardless of whether or not the trailer is plugged into the tow vehicle. Im assuming it is because there is a battery in the travel trailer providing power through the plug. Is this something I should be concerned about or is it okay to always have the light on?

Your trailer battery is the reason the 12 volt accessory circuit on the 7-way part # HM48503 is lighting up all the time. It's voltage is backfeeding to the connector and lighting the LED.
This LED draws such a low amount it would take a very long time to have any real impact on the battery life. Since inactivity naturally drains batteries the battery would have already drained from inactivity before the light would drain it due to it's very low amperage draw.
