PHILIPS X-tremeVision Plus - H4 Headlight Car Halogen for Universal for Car (12 V, 55 W)  (Universal For Bike, Universal For Car, Pack of 2)

These are the extreme vision plus series and an upgrade from the xtreme vision series. I found the light output to be marginally better than the stock lamps, however the focus of the beam especially in the low beam is exceptional. You would be able to notice a coin lying on the road from around 40~50 meters .
Light output wise if you're expecting flash your lights and bring truck drivers to submission these aren't meant to be that way.
You will get much better focus and slightly better light ...

Tad better than OEM and not bright enough to attract a challan. Its an option between OEM bulbs and LED. Whiter than OEM bulbs.

super bright
