The Pontiac G8 comes equipped with halogen bulbs for all its exterior lights. LED lights are a popular G8 option as they last longer than halogen lights and are much brighter. If you wish to install LED lights into your G8, you need to purchase LED light assemblies as LED bulbs require different wiring than halogen bulbs. The process is fairly simple and you can replace the assemblies in a matter of minutes, provided you have the appropriate tools.
