Is There Lighting Kit for 2020 Honda Civic Towed on Tow Dolly

Updated 01/07/2026 | Published 01/04/2026

Question:

I pull a 2020 Honda Civic behind my RV on a dolly. I would like to wire my Civic tail lights to be in unison with my RV tail lights. Do you sell a kit that does that? TIA Matt

Hey Matthew, we have tow bar lighting kits available for your 2020 Honda Civic like the Roadmaster diode kit part # RM-15267. These diodes wire into the taillight circuit of your car which then allows the tow vehicle trailer light circuits to control the Civic taillights.

Does the dolly have taillights built into it as well?

Unfortunately it does not. How difficult is it to add the diodes? Thank you.

@MatthewH It's not crazy hard but you do have to splice them into the vehicle taillights. While we don't have an install video for a 2020 Civic yet I did attach one for a 2020 Accord for you to check out that will show you the process.
