LED Bulbs

LED bulbs are the most efficient light source and produce white light very similar to natural daylight. Most commonly used in vehicle interiors, as LED headlamps are not approved for use in many countries or the legal specifics can be murky. Before purchase, make sure your chosen model has appropriate dimensions and a compatible socket.

Car sockets and their most common usage

  • SV8.5 - number plate, side marker lights, reading lights, interior lights for trailers, caravans, boats etc.
  • T5 - dashboard
  • Ba15s - turn signals and taillights
  • T10/BA9S - brake lights

Basic LED bulbs parameters

  • Luminous flux - light output (how much light the bulb produces), measured in lumens (lm). It is equivalent to watts (W) relative to the average sensitivity of the human eye.
  • Colour temperature - colour temperature (or chromaticity) characterises the white light spectrum (kelvin - K). Depending on the value, we perceive light as "warm white" (about 3000K) to "cool white" (6000K).
  • Lifespan - LED bulbs have a much longer lifespan than classic lamps. They are shock-resistant and particularly suitable for places where light bulb durability is an issue.
  • CAN-Bus Ready - prevents false “broken light bulb” warnings caused by the computer system in some newer cars

LED bulbs and certification

In some countries, LED bulbs are not approved for exterior use in motor vehicles or trailers. If you want to drive your car on public roads, then you probably shouldn’t replace your current bulbs with LED bulbs unless you are absolutely certain that they are fully certified and approved in your country.
