tail lights.

This weekend My tail lights went wacky.



I get a ding in the cab starting up, Then if I press the brakes, I get the same beep. I only get the rear brake light on the cab when I press the brake. I only get right blinker. When I put it on left blinker I get the ding and fast blinking. All lights on the front of the truck work. Cab brake light works. Right Rear works. Both reverse lights work. Both plate lights work.



Please don't tell me it is the control module.

When it is fast blinking, is both the front and rear blinking? Is the bed left brake light working? If yes to the latter, then yeah it might be the TIPM

 

[y22man]

When the fast blinking (on the driver side) No, only the front is blinking. The right side does not fast blink.

You have a bulb out.

Then change the left rear bulb

Sure enough rear driver bulb. Looked ok. Changed it and all is well. Thanks again.
