Tying in Brake Lights & Turn Signals of Trailer to Separate Lights of Isuzu
Updated 02/03/2026 | Published 07/20/2024
Question:
I have a 2019 Isuzu npr, it has separate brake and turn signal bulbs. I tie in to brake signal, trailer brakes work but because the turn signals are on a different circuit than the brakes trailer brake lights aren’t working. I’ve tried everything, how can I get brake signal to turn signals on trailer. Thank you

Hey Josh,
From what I can tell from what you're describing, what you need is the Roadmaster Brite-Lite Wiring Converter # RM-732. This will allow your trailer's brakes and turn signals work in tandem with your Isuzu's.

Hey Josh, how did things go with the Brite-Lite wiring converter on your Isuzu? Did it get your trailer brake and turn lights working together like you wanted? Your update could make it easier for others with the same wiring setup.
