LED Headlight Bulb Orientation Guide
One of the most common questions we hear every day is how your LED bulb should faced or aligned. LEDs are a “directional” light sources, which means they emit light in a specific direction, unlike halogen, which emits light in 360°. The light will otherwise appear to have poor output or beam pattern, not to mention the glare may cause the other drivers. That's why LED bulbs have to be positioned correctly according to the different optical design of the headlamps.
First, we need to decide whether your headlight is Reflector Style or Projector Style.
For reflector Style headlamp, the position of the diodes (LED chips) should always be in a side to side orientation, meaning, you should have one set facing at 3 o’clock, and the other set facing at 9 o’clock. This will allow a nice and even 360 light distribution throughout the housing creating an even beam of light as well as evenly fill up the housing.
For dual headlight setups, that provide low and high beams off one bulb, will use the same orientation side to side orientation. There are two sets of LED chips on both sides of the bulb for dual beam bulbs, the two chipsets need to be aligned according to the illustration as below.
For reflector Style headlamp, we offer the Projector Specific LED Bulbs which has only one diode (LED chip). The LED chip should always be facing upward, meaning, you should have it facing 12 o’clock.
IMPORTANT NOTE: In most cases, all bulbs are initially set to an optimal operating angle and adjustment is not always required. Check the bulb orientation right away after you put the LED bulbs in before any harness is connected. All of our LED headlight and fog light bulbs has adjustable collars, you can easily Adjust The Bulb Angle By Clocking The Collar Of The Bulb. In case the LED bulb is not sitting at the correct angle, you need to adjust it to the right angle.
