Convert your sealed beam headlights to H4 halogens with this premium quality kit.
Koito H4 lamps were an easy selection for Best-in-Class as they are clearly superior to all of their competitors. Made in Japan they are:
- More efficient which creates more light on the road
- Better focused which creates a more useful distribution of light
- Higher quality with sturdier glass and metal materials and more carefully built quality than their competitors.
You will need H4/H5 adapters if upgrading from H5 headlights.
These work brilliantly with our Best-in-Class Tungsram Ultra MegaLight +120% bulbs.
A premium product at a premium price - just like your Porsche®
Beware of counterfeits of these headlights. You will find them for sale here and there for ridiculously low prices which means a cheap product is being fraudulently rebranded, in other words, counterfeiting. The old cliches that there is no free lunch and you get what you pay for have never been so true.
