Footnote: I also installed Xenon bulbs, but only for the front low and high beams. They were originally Eurolite H1 and H7 55W bulbs. I must say that the Eurolite bulbs are a waste of time, and in no time at all I was looking for something better. John Gordon introduced me to the PIAA Xtreme White bulbs and these were a dramatic improvement! Bright, white and almost like HID. The beam pattern is also much wider than stock. Thanks to John, you can check these photos out for a great comparison between Stock, Sylvania Silverstar Xenon bulbs, HID [Photo 1, Photo 2], and Roadmax Xenon bulbs [Photo 1, Photo 2]. John thinks that the Roadmax bulbs are brighter than the Xtreme Whites but you be the judge [Photo 1, Photo 2 and Photo 3]. One thing is for sure, the Roadmax bulbs are a better buy as they are cheaper. -- Wayne.
None of the aftermarket bulbs that you get with some kind of coating to the bulb will be more luminous. I've tried many brands over the years, from cheap ones to the very expensive PIAA's from Japan. I prefer the OEM bulbs over any blue coated bulb on the market.Al & Colleen said:hi all , just bought artic wite light / relpaced stock but im not getting the effect i want. still not luminius enough, was thinking on removing the cap that sits over the light bulb .??
