2007.5 6.7L Headlight Issue

[Mark Craig]

Help my truck is possessed!!! Three bulbs in the drivers side headlight sine 2009. Got pulled over again last Friday night the stipud thing is out again. Smacked it a few times while I was being checked by the Local Mountie!! Luckily it ws a dry evening or he'd be getting me for DUI I guess. Anyway went out Saturday to get a bulb got busy and never made it to the store for one. Headed home and I'll be the dumb thing is working just fine highs lows everything.



I can't keep this up as I am gonna run out of luck. A DOA headlight gives any police the reason to pull over for anything.



Connections are good no corrosion at the end of any of the wires, checked by tugging a little on the wires to make sure they are IN the connector well too all is OK. Suggestions???

Check for loose connections on the ground. You can get a wiring diagram from Dodge's body builder site. I'm guessing that it would be grounded either next to the driver's side battery or just behind the battery on the firewall. Some people have had problems with the grounds corroding due to battery acids, as well as having the threaded insert come loose from the sheet metal.

Any loose connection will cause the bulb to burn out quickly. (It causes the bulb to flicker on and off, which is much worse on the bulb that just being on).

Let us know what you find!

Headlight mess

TLane,



Thanks but it is not burning the bulbs out, I bet the first three I replaced were fine but they are long gone with the trash now. The dang thing just decides to stop working and then start working when it decides it wants to. Grounds aren't usually that finiky... are they??

I had responded in the 911 post.



Grounds can be that finecky but if the grounds are OK, you may have a pin in a harness that is partially backed out or the wire to that pin may be a marginal crimp.

If there wasn't a good crimp,corrosion will build up between the wire and pin and cause higher resistance and ultimately the problem you are having.

I have had the same issue with my truck. Found it to be the plug connection at the pigtail. (think that made sense) The connectors were loose had to push them back in and take a pick tool and spread out the retainers. hope this helps. Solve my issue.
