I'm new here so please go easy on me!



I recently had three Hella Rallye 4000 Eurobeam's (100 watt halogen each) installed on a pre-runner bar on the front of my truck.



Tonight I was curious and took one apart, and found that there is actually TWO bulbs in them. The main one is a 100W H1 halogen, but then there is a smaller one at the bottom center of the lens. This bulb is a 55 Watt.



What purpose does this 2nd bulb serve?



I looked on hella's website and I think I might have the Eurobeam with position lamp option. Any one else have these or know why both bulbs are used?





Thanks!
