Headlights work but when on cause lamp out and chime 2003 Dodge 2500

Asked by Mar 03, 2017 at 09:06 PM about the 2003 Dodge Ram 2500 SLT Quad Cab LB

Question type: Maintenance & Repair

After replacing headlight assembly due to
yellowing on my dodge 2500, the turn signals work
fine except when headlights are one.  If headlights
are on I get a lamp out on dash and chime when
using turn signals.  Replaced all lights even though
they were all working.  Did not see any damage to
any bulbs.

Check the sockets and the ground supply to the headlights, the light out system relies on ohm readings so somewhere in the headlight circuit there is a higher than normal ohms reading, I have only had 1 bulb cause that kind of problem and when you looked carefully at the lamp you could see one of the filaments had broken off and welded itself to the other filament, it did cause a feedback into high beam circuit but also a light out on the control panel.
