i have brake lights and turn signals and headlights but no running lights in the rear. need to get fixed and show proof to police officer to ovoid a ticket

 

Do you have front running lights?

 

yes the fronts work

 

I believe its a brown wire that feeds the marker circuit. First look along the frame rail and in the rear for any damaged wires. If you have a test light or voltmeter check for power on that wire on the frame rail. If you have power, follow it back and try to figure out where you lose it.

 

There might also be a plug at the rear of the truck somewhere aroung the drivers frame rail. Might check if theres any corrosion there....

 

oh boy.that's a pretty dangerous one.he must be having a good day to issue a warning.
start with the basics first of course,the bulbs.

 

X2 on this, or a broken wire at the same square plug location.

 

also check grounds and any trailer wiring connections, as those can also be points of trouble. i've seen some pretty bad trailer plug wiring jobs.

 

let's all hold up one minute........


we have rear running lights?

 

they're also called taillights, the red ones back there that are dim when the headlights are on then get bright when using the brakes or turn signals... yeah, those

 

yes we do...don't you? Tag lights and markers on the same circuit.

 

ah....those lights.

 

Wow...94...that had me giggling XD! ANYWAY...i know the solution to THIS! My 84 did this and after battling for a year with it....i finally fixed it.

 

Guess I should probably post MY solution:

Its caused from a bad ground...trust me....the ground wire at the rear running light....take that, cut the bloody thing and drill a hole in the bed somewhere inconspicuously like...put one of them thar U shaped doohickeys on the end of a New wire....splice it to the current ground...attach...and then tell me what happens....
