Turn signal on when braking??

[SilverBullet75]

Strange thing happened this morning...
Noticed that every time I hit the brakes, my left turn signal comes on (instead of the brake light).

Is this a "fail safe" when a bulb goes out?

I'll check everything out when I get off work, but right now I'm disturbed by this...

Thoughts?

First thing to check is your trailer light adapter wiring. If it's not getting a good ground, then really funky things can happen ... ask me how I know!!!

I do have trailer wiring, but haven't used it in about a year. I'll check into it. Thanks!

Yah, when mine started acting up, I hadn't used it in a while either. Unfortunately, I was in the process of wiring in the replacement when I found the loose ground wire.

Agree with Tom. Also are you using standard bulbs or LED bulbs? I have seen many people have issues with LED bulbs in the tail/turn signals. Sometimes you need load resistors across the brake lights in addition to turn signals. try using that turn signal when you are on the highway with cruise control engaged. If the cruise control disengages you have a short or bad ground. If it doesn't you probably have two wires backwards or an incorrect/misplaced bulb

Hi,
No LED. Just stock.
This all happened suddenly this morning.

I'll try the cruise trick too.
thanks!

Hoping it's just a blown bulb...
