Can The Lights Of The Hughes Autoformers Watchdog Surge Protector Be Dimmed  

Updated 08/14/2026 | Published 11/22/2024

Question:

Is there a way to dim the lights from the watchdog? It shines right through our trailers window even with the shades closed.

Hey Sean,

The Hughes Autoformers Adhesive Dimmer Shade # HU28VR is exactly what you need. This shade just has a 3M backing to stick to your Watchdog Surge Protector # HU67FR (30amp) or # HU87FR (50 amp) to dim the LED's to something more acceptable. This would also work for the hardwired versions (30 amp # HU77FR and 50 amp # HU27FR ) if you have them in a spot where the light could potentially be an issue.

Hey Sean, did the adhesive dimmer shade help cut down the light from your Watchdog surge protector? Knowing how well it worked could help others dealing with the same bright LEDs in their trailers.

Is there one for Gen2 versions?

@PatG Great question! For the second generation of the Watchdog surge protector, Hughes Autoformers built a dimming feature directly into the Gen II hardware and app. The app will let you set the faceplate illumination from completely off to full brightness.
