Moisture in the headlights deteriorates the quality of the light beam and is at the top of the list of rejection points in the annual vehicle inspection.
With the B-quality H4 headlight unit and the sealed beam replacement there is a rubber cap over the place where the H4 bulb is clamped in the headlight unit, if this rubber is torn you will have to replace it.
Attention : Please note that this rubber is only intended for specified headlights and is not suitable for the original Hella.
