Folks,
Just upgraded my Santro bulbs to Philips Vision Plus H4 Bulbs. They are really awesome and much better compared to the Philips Blue/Crystal vision. The beam is really good and even the throw (length) is better than the other bulbs.
I got the truck drivers to dip and dim with Vision Plus 50/60 Bulb. The cost is 230 Rs per piece. Upgraded my Bullet also to Vision plus with a Lumax dome and the results are awesome.
Extract from Philips Website:
All about the VisionPlus bulb of Philips
50% more light on the road!
Philips Vision Plus is the award winning ultimate vehicle lighting upgrade and can be fitted simply and quickly for less than the price of half a tank of fuel.
You may feel relieved that your car has technical safety features such as an airbag and ABS. But would it not be better to avoid situation where they may be needed by simply fitting better lighting?
Scientifically, it has been proven that as we get older we need more light to drive safely, for example a 40 year needs twice as much light as a 20 year old even more so when driving at high speed and statistics show that 60% of traffic accidents happen during hours of darkness or bad weather.
Better lighting acts as soon as it is switched on and allows ABS to be more effective by increasing the "safety distance" and enabling obstacles in the road to be seen much earlier.
Vision Plus will also make long journeys safer, Vision Plus will help with the concentration and effort needed, during night time driving leaving you feeling less tired and more refreshed upon arrival at your destination.
Here are just some of the benefits you'll see:
Up to 50% more light on the road
20 metres longer beam
Better reflections from road signs
UV resistant Cut Quartz safe to use with plastic lenses
Optimises colour temperature to give deep white light
Interchangeable upgrade with existing lamps
Fully Compliant with ECE Regulation 37
But don't just take our word for it! Here's what Auto Express said about Philips Vision Plus in their 2003 Autobulb test...

"Philips' top-of-the-range option is a superb bulb which performed comfortably ahead of the plus 30% premium versions. You just cannot ignore the performance, which is why the Vision Plus merits our Recommended award."
