Re: Rear end Light Bulbs 22nd series

The Mazda numbers are an old designation and has nothing to do with the current car brand. Just asking for an 1158 or whatever at the parts store should be sufficient.
Here is the bulb number needed in a particular location from the owners manual and some more detailed specs correlating the Packard part number with the Mazda number and info on base contacts from the utility section of parts book. The candle power designation is the amount of light the bulb puts out and in the case of the 1154 or 1158 it means one filament puts out 3cp which is used for the tail or park light and the other is 21cp which would be the turn signal or brake light.
One difference on 22nd series could be the turn signal bulb. There is some question on when Packard switched to the "modern" turn signal system which utilizes the same rear filament for brake and turn signals. In 47 and earlier cars the rear turn signal bulb was separate and only used for the signals. It was an 1129 which is a single filament bulb at 21cp. The question arises because early 22nd series also used that same independent system but the owners manual shows only the shared bulb used in 23rd series and later cars. Unknown when the change was made as the 22nd series wiring diagram only shows the independent system.
Backing or reverse lights were an option and bulb can vary by year and type of housing and whether the reverse light was the factory or a dealer installed and possibly aftermarket unit. Typically they use an 1133 bulb but that is not a set in stone rule.
