I have a Ram 3500, 4x4 diesel. I have an indicator light on the central dash display that says i have a lamp out. I have been through the whole truck several times and everything seems to be working. Anyone with an idea??

 

dumb question, but did you check the turn signals, and fog lights.

 

If they are on the verge of going out, it'll pick up on that. Have someone push the brakes and look at the rear.

What year? Might be one of the rear circuit boards. Had this happen to me.

 

Sure did even lic plate light everything seems to be working

 

Thanks been this way for a year now and all lights check out ok

 

It's an 04. Thanks

 

i would agree the tail lights might be working but a faulty circut board wont draw enough, which might trip the light.
