Ram 2005 headlight bulbs

Scatter....mostly on USA DOT headlamps. E-Code lamps typically do
NOT have much if any at all...

That 'wing' is to light up road signs and pedestrians on the side of
the road

I too do NOT like HID's. Too high temp and washes out detail. So
much so, that it is NOT good if the level between eyeballs and light
source is too close. No shadows...therefore no depth perception, for me...

On HID's in lamps NOT designed for HID's...the point or source of
light is very different between their bulbs.

The engineering is out of wack when an HID bulb is placed into a
headlamp designed for a tungsten filament bulb. The size and shape
of that light source is different...therefor the the higher amounts
of scatter. Even in an E-Code lamp designed for a QH bulb


PS...guess which images below are of DOT headlamps and the owner
modified it with a 'shield' he mounted inside the lamp...hint...it
still has scatter above the cut off...because he is only dealing
with lens and the headlamp design also includes the reflector...which
he did not know HOW2 change...

There is very little 'scatter' from 'good' lens. Both design and
materials...better ones have 'lead crystal', not glass, not plastic.
Lead crystal because QH bulbs run so hot, they can melt regular glass.
Also why OEM QH with plastic lens/housings have loooong runs with small
wire gauge to knock down the voltage so they don't burn as hot.

Scatter is what bugs most folks. Worse if the main beam shines into the eyeballs.
This is why many enthusiasts go to E-Code and toss the DOT code OEMs.
Poorly designed fog lamps will have scatter above and then makes them
almost useless as fog lamps.

Plain E-Code low's 'would' make good fog lamps if they were low enough.

Here's a set of pictures of an E-Code beam pattern. Notice the lack
of scatter above the beam pattern. Notice the 'wing', which is mandated
by specification. It's to light up road signs, pedestrians, etc.

Typical E-Code beam pattern:
e-code



E-Code Z beam. Notice the 'wing' is clipped.




Another E-Code beam pattern, but with the drivers side wing removed:



This is the drivers side head lamp with the removed wing:




Here's a head on with the same vehicle. One with OEM and other after
he switched to E-Code. Same height and same angle in reference to the
vehicle.
