1965 courtesy lamp

Hi, will be tackling under dash courtesy lamps on my 65 hardtop in the coming weeks. What is see under the passenger and driver side is two black wires, one with a white stripe and the other with an orange stripe and no existing sockets. I found a wiring courtesy lamp harness online that I'm considering, it has a white and orange wire, both solid.....not sure if that will work. Also considering buying sockets from the local parts store some have a single contact and others have double contacts on the socket.

Grateful for your thoughts!

Welcome to the Team Art!

The bulbs are generally single terminal (contact) Unless you want a blinking light or a sudden increase in lumens, then the turn signal/brake and regular coach lamp will work.

Newer cars such as my 1985 Impala all used orange and white colored wires for the dome, map reading, periscope and courtesy lights (inside the glove box and the center console also used the same colored wires to power the light, but had a smaller socket for the screw in 1895 lamp instead of the 1003 lamp used for a courtesy light).
You will have to find the socket (called a pig tail), and the reflective cup that is supposed to reflect the light back (it is just galvanized steel so it fails miserably as a reflector) along with the mounting bracket that bolts all of this in place.

In your case there are two different sockets and two different lamps that fit the different sockets. The standard interior used the standard light which would be the larger of the two options with the double contact, This is a 90 lamp and socket. In the deluxe interior option there is a smaller (called a miniature but it is still huge by todays standards) that uses a single contact socket and lamp that bears number 631.

I would look into LED replacement lamps in place of these which will be hard to find unless you are going for a chalk mark correct white glove concours judged restoration where they count off if you are not using Old Spice or Brute cologne (the two most popular male fragrances in the sixties).

My 65 convertible has the under dash lights. I'll have the cover off sometime this week to get it out for spring, so I'll check the wiring for you.

Two doors, four doors, wagons, and ragtops.

Thanks for replying Dave, great insight! Jason, keep me posted!

A little background...........My Dad bought this 65 used in 1975, I was 4 years old. It is the first family car I have memories of. As you know, such memories are priceless!!! Thanks again!
