Cigarette Lighter identification

[zed1]

I need help identifying a couple of Niles cigarette lighters I have.  

 

Any information about the year and model Datsun/Nissan these were originally installed is appreciated.

Thanks,

Keith

I would say that the bottom one is at least a 70-72 510 cuz has the same grooved pattern as the wiper & headlight knobs.......I just sold those to a guy.

 

The top one is a plain knob, so my guess is early trucks..........I think my 1974 620 parts truck had a bigger one, so maybe before 1974...........??

i have the bottom one in both 510s since ive owned them, seemed original.

works too!
