Due to poor lighting at night, I always have trouble driving in the dark, especially without street lamps and relying solely on the car's headlights. I do not own an exotic car, so I'm using standard halogen lamps. Thankfully, you don't need spend so much upgrading to HID (which is also illegal in most countries unless it is an OEM one) to get any sort of improvements. There are many after market light bulbs from Philips, Osram to choose from. My priority is maximum output, better range, but without being illegal. So no 100W bulbs, no HID modifications. Just direct bulbs swap. I only choose between Philips or Osram simply because of their huge market in lighting industries. I was using Philips Vision Plus which claims to improve by 50% over stock bulbs. I do not have measuring equipment to prove that. But it is noticeably brighter, and has longer beam. The life span is also shorter than OE bulbs. The bulbs died few months ago, so I had to look for replacements. It narrowed down to Philips and Osram again, Xtreme Power or Night Breaker. Night Breaker is noticeably cheaper in MY, around RM120 compare with RM180 for Xtreme Power. Since I had good experience with Philips, I've decided to look elsewhere for cheaper Philips bulbs (outside Malaysia)... Powerbulbs is where I got the Xtreme Power from. It has free shipping, and come with free sidelight bulbs! And still much cheaper then MY. Delivery took about 14 business days, not the speediest delivery, and I actually emailed them suspecting that the shipping could be lost. Since Trinity brought up the question about blue tint bulbs, Xtreme Power is very close to stock color temperature, which is slightly yellowish. Perfect compromise for good brightness in both dry and rain conditions. It is also important that your headlamps are aligned properly so you don't blind any cars in front of you. I have not installed the bulbs yet. But hopefully I will have a chance to compare my cheaper bulbs vs this Philips Xtreme Power bulbs.
