For 55/60 watt bulbs, Philips Xtreme vision is your ultimate choice which comes at a heavy price.Its a plug n play with almost any modern cars.
If you want to upgrade - please use a relay ( Hella or Philips). It comes as a kit - so you get relay, wiring and ceramic holders. Will cost 500-700 based on the location/shop.
For 90/100 watt bulbs - I have used Halonix. Its very cheap. Yellow light output and decent. Cant complain.
Recently switched to Philips 90/100 Essential vision for better and longer throw. These are bright and white. Not show off type white but just plain white.
Philips diamond/crystal visions are good for normal city driving. For heavy use at night I would not recommend them at all.
