Front panel needs to be visible from below and in bright sunlight.

Front panel and operation status LEDs need to be visible from below and in bright sunlight.

Units from other vendors generally angle the front panel downward, design the case so the LEDs are visible from directly below, and/or use very bright LEDs.
