HB4 9006 LED bulbs and kits

HB4 and HB3 bulbs have a very similar base, but with a locating tab positioned differently, they are therefore not interchangeable. The HB4 (9006) is generally used for low beams or fog lights, while the HB3 (9005) is dedicated to high beams. If your vehicle uses both types, also check out our category HB3 9005 LED bulbs for a complete LED conversion.

Installation is simple: open the hood, access the rear of the headlight, turn the HB4 bulb holder a quarter turn to remove it, then insert the LED bulb. Kits like the Titanium XS V2 have a compact format, which makes it easier to reinstall the rear cover of the headlight. The operation takes about 15 minutes per headlight.

The choice depends on the space available behind the headlight. The ventilated GTS 1.1 EVO offers better heat dissipation and more stable brightness, but it is slightly longer. The passive LP1 is more compact and quiet, ideal for headlights with restricted rear access.
