I replaced my headlight bulbs and I don't know if it is coincidence or not but my rear marker lights are not working. My brake lights work but no rear marker/ running lights. The front ones work but no rears. The reverse lights work also. I did tow a trailer the other day and did a late night drive through the timber last night so anything may be possable. Is there a seperate fuse for the rear tailights or is it a wire issue? I do have led tailights. Thanks for any help.

 

You are refering to the ID lights correct?
The ones in the middle above the bumper?

 

The trucks running/parking lights are all fused together. There is a separate fuse for the trailer markers though.

Sounds like you issue would either be with both bulbs being burned out, maybe not at the same time but most noticeable without both, or wiring issues.

 

Well he has a 250 and I dont think they ever came factory on a 250 since they were for DOT compliance for DRW trucks. I'll bet the ID lights are wired into the 7 pin marker lights. Which, as you pointed out, would make them a separate fuse.

 

I am talking about the tail lights that are in the body. There is reverse and brake and tail lights/side marker lights in the same housing. Mine have been replaced with smoked recon? led housings. The big lights on the back on either side of the tailgate. They are led so I wouldn't think both rear and side marker LEDs went out at the same time. All worked two days ago.

 

Now my turn signal flasher is faster than normal

 

I doubt your LED running lights both failed at the same time. A fast flasher means that less current than normal is being drawn, either from burned out bulbs or a wiring problem (I'm assuming the flasher used to work normally with the LED's). Since all the running lights are protected by the same fuse I would look at the wiring first.

I think it's a wire problem now also. I recently did the hutch mod and removed the bed to do so. This morning I unpluged the harness by the bumper to check it and things got worse. Gona have to start there I guess. Good thing I live and work in the country no rear turn signals and brake lights would be really bad if I had to drive in the city. Hope I can figure it out before the ride home.
