Frequently asked question · beam pattern

Will I get a good beam pattern with xenon or LED in my low beam?

Yes, if it's good with your standard bulb now. The focal point of our bulbs falls exactly on that of the original filament, so you keep the same neat beam pattern, just a lot brighter.

Short answer

Yes. If you have a good beam pattern with your standard bulb now, you'll have it with a Hilox xenon or LED kit too, just with more light. The focal point of our bulbs matches that of the original bulb exactly.

A good beam pattern stays a good beam pattern

If you have a good beam pattern with your standard bulb, you'll have it with a xenon or LED kit too, just with a higher light output.

The focal point of the light source

The beam pattern in a lens or reflector headlight is largely determined by the focal point of the light source. If that sits exactly in the right place in the projector or reflector, you always get a good beam pattern and your car, motorbike or truck passes the annual inspection.

Important: if you replace the standard bulb with xenon or LED, the focal point of the new bulb must match that of the original bulb exactly. Our xenon and LED bulbs are made by machine with extreme precision and every product is checked to the micrometre. On the H7 XTR Black you can see it for yourself in 3D: switch on "Compare with halogen" and the LED's light point falls exactly on that of the filament.

Exceptions

Not every vehicle manufacturer makes a good headlight. So the quality of the beam pattern depends heavily on the headlight itself. If the beam pattern with the standard bulb is already poor, it won't get better with more light, assuming the standard bulb is of good quality.

Other causes of a poor beam pattern:

The bulb sits crooked in the headlight
A poor-quality headlight
A poor-quality light source whose focal point doesn't match the original bulb

After damage, cars often drive around with two different headlights, one of them of lower quality; the light colour often differs too, even though nothing is wrong with the bulb. Tip: after damage, don't skimp on the headlight and have a new one fitted of the same make and type as the original, or replace both headlights.

If the beam pattern is poor because of a low-quality headlight or light source, solve that cause first.
