These 'globes' are a replacement for normal halogen ones. I fitted them in an EF Fairmont - they give you a whiter light and seem make seeing easier. Whether they give you 30 to 50 % more visibility than normal halogen as claimed, can't say.
DO NOT confuse them with the Euro/Jap PULSE XENON lamp which is a 50 volt system. The 50 volt comes via a 12 - 50 volt transformer. For most Euro cars 95 on, Hella and Bosch make kits to retrofit to existing vehicles. These are a gas discharge lamp which pulse many times per second, emitting a high intensity bright white light. Look for them in the 2000 year on model Merc/BMW/Nissan Skyline/Lexus/Subaru B4 or GTB, Porsche/Audi/VW/Toyota/ and probably anything else modern that is not a Ford. I expect Ford will release them in about 2 models time. Holden will probably pick them up and run with them first, then Ford will then decide to copy.
