Yes - i was just trying to determine if it is the circuit breaker OR head light switch at fault -- Thanks

That's what I was afraid of. I Thought I had found something good. Is there any other way to verify if the breaker is bad, other than pulling the assembly out ? I Sure don't look forward to that.

Another question on my 1948 Deluxe wiring problem - I found that my cigar lighter is working fine . Since the cigar lighter comes of the head light switch/circuit breaker, does that mean that the circuit breaker is OK ? I am talking about the circuit breaker on the head light switch . Thanks

Thank you so much - I am getting an education in Packard wiring !

That's good to know- I thought they were separate. Does that mean that the brake light goes thru the same circuit breaker as headlights and tail lights ? I was able to look up under the dash -everything looks nice and clean.

Thanks to everyone - I see the switch - dont know if that is the problem or the wires , got to start somewhere. Could low brake fluid in the master cylinder cause this too ?

Can someone tell me where the brake light switch is on my 48 Deluxe. A picture would help - I have no brake lights Thanks

Thank for any info on my 48 Deluxe. - I may need to remove the head light switch and circuit breaker. Do I have to remove the entire switch assembly to get to the light switch and breaker. I think the breaker may have quit. Thanks

HH56 - I have the wiring diagram for the rear lights. I MAY have found what caused this problem. The original drop down wire to the license plate has been cut, and a new wire run from the license plate light to one of the incoming square connectors. I dont know why this was done unless the original wire had a break. Looking at this wire from under the car, it looks like it could be shorted where it comes thru the grommet. So, I think I will unplug this wire from the square connector and remove the license plate light assembly. IF this is the problem , I can correct it. But still dont know if the circuit breaker will reset - probably not.

HH56 -Thanks again for your support. I agree with what you are saying. Yes. I have been looking at all the wires in the trunk. This all started with just the right tail light not working. After I installed a new bulb, it still did not burn. So - I decided to check the bulb in the left side to confirm that I had the right bulb. Both were 1154. The owner manual says the tail and stop should be 1158 and the parking and direction signal light 1154. ( your comments on this ) So, now I have no head lights, no tail lights . It seem that MAYBE I shorted some wire as I was checking , and tripped the circuit breaker. I will look again for a short around the license light and left side. Do they plug in ? I do not want to pull the dash switch panel out to check the circuit breaker unless I have to. Here are some good pictures of a 1950 control switch panel under Electrical & Fuel -page 1 , posted on Aug 4. I assume the 50 is same as my 48 ? I do not know why the circuit breaker did not reset , unless it is still shorted or ruined. Thanks
