Review of Philips Diamond vision 5000K 55/60W H4 Car- Alto LXi
Bulb Vendor- Amba Sales, 1/7, Nicholson Road, Kashmere Gate.
My hunt for a headlight bulb began after I did some extensive night driving in quite unforgiving terrain. Reading the forum, I decided on Osram Silverstar but, later dropped the idea because of warranty issues & also because Philips authorized distributor offered on the spot exchange facility.
I browsed through the Philips range & found Diamond visions to be giving the whitest white light among halogens as well as being near equal in terms of reliability when compared to stock halogens(Halonix).HID bulbs also interested me, but, the cost overheads put me off. Auxillary lights on bumper will most probably be vandalized/broken on front impact & roof lights looked too awkward & were against RTO norms
So, I bought Philips Diamond vision 60/55W H4s. Now, came the fitment.
After doing some experimenting, I was able to yank the stock bulb off and put on these babies. I waited for sundown & boy, I was thrilled. These bulbs give upto 40% more light than stock halogens in pitch black & 20%+ guaranteed in all other situations.They generate a little more amount of heat than stock & don't void electrical warranty. These are the best stock upgrade bulbs you can get from Philips.Period.

More light than stock bulbs while being of stock wattage
Attention grabbers, Scream Look-at-me on high beam
White light captures better detail in terms of foliage & terrain
Easy on the eyes for pedestrians(tested by myself)
Genuine Imported part & ready replacement
Lifetime Warranty -ves
Price= Rs. 800/- for a set of two
No blue pilot light/parking light included in the package which seems awkward Overall A nice set of stock upgrade bulbs. Completely fool proof & best if you don't want a complicated setup/warranty issues/HID expenditure. Now, only if they provided a parking lamp
Getting Blue Vision parking lights & number plate lights soon  .
