RE: more euro lights - light pattern question

["Browning David (TVCS)" <BrowningD@tce.com>]

I have a feeling that the bulb itself may make some difference, but I'm not
exactly sure.  For instance, I replaced the 55W H1 bulbs in my 4000's
driving light with 100W's.  I had to readjust the beam in a big way.  I also
think it wasn't as "focused" as the 55W, so I put the 55W's back in.

'86 4000s (H1/H4's)
