the main drawback to the pop ups are lighting options. most buy the ebay setup with or without HID, some dish out the cash for the Pegasus lights, and others swap fronts. The non HID ebays have terribly poor lighting while the HID version is responsible for blinding all of us. Pegasus make an excellent product as far as function goes, but they look awkward imo and the $200+ price tag isnt exactly practical. I was stuck using the Kragen Sylvania Silverstar sealed beams until now.
For $100 Hella makes a complete H4 conversion kit which includes a Left and Right headlight with special E Code lenses, two H4 bulbs, and two rubber boots to cover the plugs. *THIS IS NOT HID*
The E Code lenses are specially designed to direct your light output properly to give razor sharp cutoff, excellent performance, and affordability. Below you can visually see how they accomplish this.
Here's a side by side comparison of the Hella's and some Ebay lights. The red lines depict where your light is being directed.
The Ebays are blasting light anywhere and everywhere, where as the Hella's show where cutoff begins, where side to side light is directed, where light illuminates the ground, and on the far right side the light is sent farther and higher to give you sidewalk/bike lane/etc visibility (this does mean you have a Left and Right headlight. Swap the two and your sidewalk vision is now blasted into oncoming traffic so please take this into account)
Hella VS OEM
some know about these, some dont. this is for the un-educated.
