Why do Torches have shiny surface behind bulb?
To be more efficient! The flash bulb emits light in all directions, but you only use the light going in the forward direction, because the object you want to light up is in that direction. If there was no curved shiny surface behind the flash bulb all light that is emitted in a backward direction is absorbed by the camera, heating it up (quite a lot actually!), and going to waste. This is about half the light! The curved shiny surface acts as a mirror which reflects the backwards light back to the forward direction, thus more light is used in a useful manner. It is shiny because it needs to reflect light (mirrors are also shiny), and curved because it channels the light into a forward direction instead of simply reflecting it. You can actually see the same mechanism in car lights!
What is the difference between the 1999 dodge ram 1500 sport headlights and the standard headlights?
The standard headlights use one 9004 bulb per side, while the sport headlights use two bulbs, a 9004 and a 9007. Light output is better with the sport headlights. This info is for model years beginning in '94 and '99-01 sport headlights. Retrofitting requires adapting the wiring to the two bulb system and cutting some sheet metal behind the headlights for clearance.
