Headlight issue

[Rob1989]

Hello gents,

 

A few days ago my headlight started flickering when i was driving into work. It has been getting worse over the past few days. Any idea what might be causing this issue? Its kinda of a big one.

Start with the easy stuff.  Check all the connectors.  Clean them off if dirty or corroded.  Check light ground connectors.  Dirty contacts or loose connectors will cause the lights to cut out.

 

After that, then look at the light switch on the dash.  It is know to fail over time.

 

Put in your signature a description of your truck: Yr., engine, trans., 2 or 4wd., any modifications done (lifts, axle swaps, etc.).  It will assist us with diagnosing your issues.

This was happening to me along with dash lights dimming and a whirring sound coming from the engine. It was my alternator. Sucker was shot. Stick voltmeter leads to the battery with the engine running and if it's only reading like 12 volts then theres the problem :D

Go to www.cruiser54.com and do Tip 3. Look at the connector featured there.

and while you're in there cleaning stuff up, now's a great time to install a headlight relay kit. :thumbsup:

^^^Yup, before your truck sets itself on fire like mine did.
