## Description

It is a perfect bulb if you are looking for up to 220% more light intensity and more white light.

Review: Night and day over old bulbs - I replaced, what I think are the original D4S bulbs in my 10 year old Mazda 6 GT. The old bulbs had no low beam cut off anymore and were more like a halogen as far as sharpness. The new Osram bulbs made a huge difference, the low beam cut-off is sharp and clean again and they are much brighter and the light output is very dense again. Replacing them in the Mazda 6 GT isnt hard, just tedious you have to drop the front skid pan and the inner fenders have to be pulled out to get to the backs of the headlights. Once in there you turn the covers that are the actual ballasts to the left 1/4 turn and they come out, then you do the same with the connector on the bulbs. I also replaced my fog light bulbs with SilverStars which made a big difference as well.
Review: Very good headlight bulbs - Bright lights. Great visibility at night. Would purchase again.
