Our H9 bulb review

If you want or have to replace your conventional vehicle lamps, you should definitely opt for an H9 bulb to get up to 20% more brightness. It is much easier to recognize obstacles or game on the road and the areas at the edge of the road are also more visible. This not only makes it easier to recognize obstacles, but also better illuminates the edge area of ​​the roadway in the dark. An H9 bulb is therefore one of the most popular lamps that can be exchanged for H4 lamps.

• H1 to H11
  The designations or differentiation of the individual lamp types is made by the designation H, for halogen lamp and a number behind it. The number after the letter gives information about the lamp type: H1, H3, H4, H7, H9 or H11.
• The technique
  Contrary to the H4 bulb, which has two filaments, the H9 bulb has only one filament. This means that two H9 bulbs each have to be installed for the low beam and driving light. Therefore, a change is only possible with a 4-headlight system. An H9 bulb connector may also help.

Our H9 bulb purchase advice

Before you buy an H9 bulb, we have to tell you that not all manufacturers are created equal. Therefore, you should follow our H9 bulb purchase recommendations and ask yourself the following questions.

What brightness can be expected?

An H9 bulb is available in different light colors, with the H9 bulb bestseller being the cold white light color with a high proportion of blue.
