Ive recently purchased a 2003 gle and would love to upgrade the light output on this car. If i do the helios upgrade for headlights and fogs, am i just changing the bulbs to each, or actually installing ballasts and new wires? What about to upgrade the fogs to HID? What exactly does high/low combo kits mean, high and low beam? Thanks for any help guys....

 

Bulbs only on top, kit on the fogs. You already have the brightest bulbs(stock) for the HID. You can upgrade for a difference in color but output will decrease slightly. You dont need to worry about high/low since we have them separated. Wires, ballast, bulbs will come with the fog kit. Pretty simple procedure.

 

excellent. Thanks for your help!
