headlight recommendation for my Duster

If your looking in the new old stock market:
6012 Might see a 2 on the glass on the older ones. nominal rating 50/40 Watt
6014 Nominal rating 60/50 watt (about 1970, although many new cars continued to be sold with 6012 for several more years)
H6014 60/40 W (around 1977)
Since 1984, with 35 watt low beam typically marked H6024 (A notable recent exception being the GE Nighthawks)

Here's some pictures of the older vs super junk Nighthawks
