A bicycle light , comprising: a light housing , a connector on the housing for securing the bicycle light to a bicycle or to a user, a battery contained within the housing , an LED circuit board within the housing , and including an external switch on the housing to provide power from the battery to the LED circuit board when desired, the LED circuit board being essentially planar and containing at least one LED in an upper part of the board and at least one LED in a lower part of the board, both LEDs directed toward a front end of the housing , reflectors positioned in the housing directly in front of the LED circuit board to reflect light from the LEDs in a forward direction out the front of the housing , a front port or window in the housing including a transparent window plate sealed in the housing , at least a part of the window plate being planar and angled obliquely downwardly relative to the LED circuit board and relative to the direction of projection of light from the LEDs , such that a lower part of the window plate is receded farther back than an upper part of the window plate, so as to provide greater depth of space in the housing for accommodating the reflector at the upper LED in the upper part of the housing and lesser depth of space for accommodating the reflector at the lower LED in the lower part of the housing ; characterized in that the reflector at the upper LED is a deep reflector producing a spot beam and the reflector at the lower LED is a shallow reflector, shallower than the deep reflector and extending forward less than the deep reflector and configured to project flood light out through the front of the housing . a light housing , a connector on the housing for securing the bicycle light to a bicycle or to a user, a battery contained within the housing , an LED circuit board within the housing , and including an external switch on the housing to provide power from the battery to the LED circuit board when desired, the LED circuit board being essentially planar and containing at least one LED in an upper part of the board and at least one LED in a lower part of the board, both LEDs directed toward a front end of the housing , reflectors positioned in the housing directly in front of the LED circuit board to reflect light from the LEDs in a forward direction out the front of the housing , a front port or window in the housing including a transparent window plate sealed in the housing , at least a part of the window plate being planar and angled obliquely downwardly relative to the LED circuit board and relative to the direction of projection of light from the LEDs , such that a lower part of the window plate is receded farther back than an upper part of the window plate, so as to provide greater depth of space in the housing for accommodating the reflector at the upper LED in the upper part of the housing and lesser depth of space for accommodating the reflector at the lower LED in the lower part of the housing ; characterized in that the reflector at the upper LED is a deep reflector producing a spot beam and the reflector at the lower LED is a shallow reflector, shallower than the deep reflector and extending forward less than the deep reflector and configured to project flood light out through the front of the housing . <EOS>
