Hi,

This question may seem silly to some but here goes. How do you tell which are the inner & outer headlight buckets? Cars in the paint shop so can't reference them. I know they mount in a particular way. Any help or photos would be appreciated.

thanks Billy

I believe the small tabs that locate them on the rear of the headlights are different.Its been a while since Ive played with a 4 light system.If I can find the buckets for the 66 Charger I can look.Rocky

Aren't the adjustment tabs on the buckets in a different place so they will only fit one way?

If you're running a 4 headlight system, you'll have 2 #4000 sealed beams, and 2 #4001 sealed beams. The Hi/Low bulb, will not fit properly into the Hi beam bucket, and vise versa. The small tabs on the bulbs are there to line up with the slots in the bucket. 69440

Thanks for the answers, new new headlights only fit in the appropriate housing.

Billy
