Hey guys i need a little bit of help with the lighting on my truck. i have a 92 250 that i bought about 8 months ago. It had a snow plow on it when i got it and whom ever put it on did a hack job on the wiring harness for the lights. This is the first dodge iv ever owned and im rewireing the turn signals and headlights. I need to know wether the lights on the fenders and the lights under the headlights are running lights or turn signals or both???The lights didnt work when i got the truck and like i said, iv never owned one of these before. Thanks for the help.

 

both are running lights and turn signals, at least mine are.

 

Correct!

Correct, sort of.

The big lights under the headlights are BOTH parking lights and signals, having double-element 1157-type bulbs.

The fender-mounted side marker lights are 194-type single-element bulbs.

They are wired such that they are grounded through the flashing side of the front bulb.

When the front bulb flashes, the side-marker temporarily loses it's ground and goes out, giving the impression that it also flashes.


I am 87.2% sure of my above statement.

 

Good point. The markers and front lights do alternate flashing. Never thought about how it works, but your description makes sense to me.
