4 PIAA Extreme white plus made the mini night driveable

So I bought my wife the car she'd hung her nose over for a while. A Mini Paceman, the 2dr cousin of the Countryman. I was immediately advised how rubbish the halogen headlights were which I can confirm is the case. Bit of research put the PIAA Extreme White Plus in the frame. They were an excellent purchase. Gone is the yellow hue, replaced by a crisp white/blue beam. There has been no need for wiring upgrades or conversions as they remain the same power consumption but are brighter and are road legal.Brilliant!

4 PIAA Extreme white H4 on Berlingo B9

Bought them to replace the original bulbs which gave good natural light but with a short beam After replacing the lighted area is wider with better visibility. Expected a little bit longer beam but still it gives better overall experience

5 Toyota Prado Headlight Bulbs

My 2006 Toyota Prado Landcrusier OEM headlight bulbs are too dim at night. These PIAA are much brighter and only took ten minutes to change them. No computer or additional warnings come on. No problem in installing them my self. Very good with at least 50% more light.
