Can the high and low beams of a motorcycle LED headlight be on at the same time?

[LaTanner]

They can be on simultaneously, but modifications are required. The high and low beams are treated as two separate circuits. When the low beam is on, the high beam has no power, and vice versa. By finding a way to power both circuits, both the high and low beams can be on together. Function of low beam: Provides nighttime illumination to distinguish objects. The low beam has an illumination range of about 30 meters. However, it features a very distinct beam cut-off line. Most vehicle low beams illuminate 30-40 meters, with the beam cut-off line at around 12-18 meters. The area in front of the cut-off line is brightly lit, allowing clear object distinction, and a clearly visible 2-3 meter diameter illuminated area on the ground. From the cut-off line to the 30-40 meter range, illumination mainly relies on ground-reflected light. This area can distinguish brightly colored objects but may not easily detect stationary dark-toned objects on the road. Function of high beam: The high beam enhances visibility and expands the field of view. On dark roads without streetlights, the visible range with high beams is significantly greater than with low beams alone. Therefore, using high beams in such conditions is highly beneficial.
