There certainly are some ' calibrated ' wires in some cars.... Ford used to use one instead of a ' normal easy to recognize resister' in the ignition ... the part where cars used 6 volt coils in 12 volt cars except for when starting... then ran on the knocked down ( via resistance wire ) 6 volts normally...

This is really more for good operation of the lights themselves than anything else.

Another useful trick is to smear the bulb base with dielectric grease before installing the bulb. The contacts will push the grease out of the way and still make electrical contact, but the grease will seal out moisture and help prevent corrosion.
