“Road legal and for context, I fitted to a Vauxhall Mokka.
To the naked eye, there's slightly better illumination in comparison to generic bulbs.
These bulbs came in at £17 for the pair in comparison to about £6 for a budget pair.
The narrow blue band on the lens eliminates enough of the yellow tint to bring the colour closer to a white light.
Looking from a distance they appear much clearer than if you inspect up close. I would estimate these at approx 4500k on the colour temperature chart (depending on how clean/clear your headlight lenses are).
If you are using standard sidelights they will appear very yellow in comparison to the Night Breakers so you may need to upgrade the sidelights too.”
“There is a big difference between the light from these bulbs and an ordinary replacement bulb.
The beam is much brighter and visibility is improved more than 100%.
I would highly recommend replacing your headlamp bulbs with these much brighter bulbs now the dark nights and mornings are here.
They are a conventional fit and anyone can do it.”
