One of the most commonly asked questions is regarding the correct orientation for LED headlight bulbs. Unlike halogen bulbs that emit light in all directions, LEDs are directional light sources. Incorrect positioning can result in poor output and beam patterns, as well as potential glare for other drivers. Hence, it is crucial to position LED bulbs correctly based on the headlamp's optical design.

For single filament bulbs, the LED chips should be oriented side to side. Specifically, one set of LEDs should face at 3 o'clock and the other set at 9 o'clock. This arrangement ensures a balanced 360° light distribution within the housing, generating an even beam of light and uniformly filling the housing.

In the case of dual headlight setups that offer both low and high beams from a single bulb, the same side-to-side orientation applies. Dual beam bulbs feature two sets of LED chips, one on each side of the bulb, and these chip sets need to be aligned according to the provided illustration.

It should be noted that most bulbs are initially positioned optimally and typically do not require further adjustment. However, it is advisable to check the bulb orientation immediately after installation, prior to connecting any harness. For detailed instructions on adjusting the angle of the bulbs, please refer to the LED Bulb Adjustment Guide.
