Bob, and Ernest,
I tried installing a 9007 in a spare broken headlight last
night. I found that I only had to file two of the three knibs on the
inside diameter of the hole that the bulb goes into. This allowde the
9007 bulb to go in perfectly, but then I started to wonder if the bulb
was upside down or rightside up. Ernest? How do you know which side is
up and which side is down?
Regarding the resultant beam patern; I shone the haedlamp up
against the wall to see the pattern. This headlamp has no lense, so the
pattern that I saw was strictly due to the reflector. The 9007 semed to
create a more defined beam pattern than the 9004. I also noticed that
the 9007 hi/lo leads are reverse of the 9004s. I think Ernest said that
I have to replace my connector as a result of using the 80/100w
bulbs without relays, so I think I'll install the 9007s. It seems to be
at least equal if not better.
I'll let you know when I get it installed.
