Strobing third brake light

Has anyone had their their third brake light dimly strobing while the truck is parked? Any idea what this could be? I have a REDARC trailer brake controller, Garmin mini dash cam and tailgate lock that are wired into the truck. I wonder if any of these are involved. Truck has under 4K miles and everything works as it should. Can’t seem to add a video but here is a picture of it on. Sorry it’s a bad picture at night but it’s just gently strobing away like Rudolph’s nose.

 

That's just the typical "It's party time indicator"

Has the confetti exploded in the cab yet?

Also, was this picture taken on a Nokia flip phone?

Oh, one more. Glad it's not a FORD. When my 3rd brake light went out, the cruise control stopped working. Why? This was FORDs way of telling you that your 3rd brake light was out. Obviously. No dash light necessary... Is your cruise control still working?

On a serious note. It sounds like your wiring is fuckey.

 

No. That’s definitely not normal. In a couple of days not being driven your battery will be out .

 

On a serious note, YES it will be one of the many aftermarket items you have added to your stock lighting.

Thanks! Turns out it’s the REDARC tow pro elite... here’s some non flip phone pictures


The dim light is what stays on (strobing to the naked eyeball) when the truck is off. The brighter one is with the brake pedal depressed.

must be the plug and play harness from redarc I’ll have to get the multimeter out and see what’s the problem.

 

Exactly what I thought of

 

Thanks, I’ll check if it goes away when it warms up.

 

Reviving this thread. Went outside this morning, temp was single digits, I am having the same exact issue. Dimly flashing 3rd brake light. Emigia, you and I have almost the same setup. I also have the Redarc elite. Have you found a solution to this?

 

I have been dealing with the same problem yet intermittently when trailer is plugged in. Replaced Tacoma connector and trailer pigtail hoping it was a bad connection but no luck. Bought another brand new trailer and it does same thing. Trailer brake are inoperative when this happens. Lights are stock on Tacoma. Anyone figure this out?

 

Ok, this is where I’m at. Bought and installed the trailer brake a couple weeks before I picked up my trailer. It was during that time that it got cold and the light started flashing. After a day or so, it was still flashing so I unplugged the Redarc harness and it stopped. The day I picked up the trailer, I plugged it back in and haven’t had the problem since. I’m guessing it’s a weird thing with the cold. I wish I had a more definitive answer.
