9006 HB4 LED bulbs
9006 HB4 LED bulbs are bulbs based on the halogen 9006 HB4 design. This means the base etc. are based on the 9006 HB4 fitment, but the light source is LED instead of halogen. A big advantage is the increase of light output, a disadvantage is usually more stray light, which can be blinding for oncoming traffic.
Also the light or color temperature is higher, which means a more white light.
Installation
Installation is usually quite easy because the base of 9006 HB4 LED bulbs is based on 9006 HB4 halogen bulbs. To prevent canbus messages / errors sometimes it is needed to have canbus cancellers.
Use on public roads
Because the 9006 HB4 standard is originally designed for halogen, most 9006 HB4 LED bulbs are not approved for the public road.
