: 1970 headlamp bulb interchange

08-09-11, 02:32 AM
Does anyone know, will the 5001 and 4012 headlamp bulbs physically interchange? I can't seem to find any reference to 4012, but they appear to be the same physical size as the 5006. Thank you.

5001-5006 fits also for a 70 according to Rockauto and will render better results as itīs a halogen lamp: http://www.rockauto.com I ordered 5001 and 5006 for my 69 (Low and High) as the ones installed were adapted european headlights and High sockets were missing. Now Iīm very happy with them :) See pic below.

Thanks for the reply. What I really need to know is, does the 4012 interchange with the 5001 or 5006? I specifically want to put a 4012 in, I just need to know if it is interchangeable.

Sorry, I canīt find that reference; maybe Itīs discontinued. I think that the relevant features to know if both references are interchangeable are diameter and type of socket plug used.
