Alongside the brilliant illumination, the LED High Performance headlamps, available on request, are characterised by a colour temperature similar to daylight and relieve the strain on the eyes during journeys at night. The low-beam headlamps configured with 34 watts work with LED projector-beam technology, the main beam with LED reflector technology. Indicators, daytime running lamps and position light are designed as multifunctional fibre-optic cables.
At the tail end of the new GLA, LED High Performance headlamps with a multi-level function are used, and brake lights and indicators are controlled in three intensities. Full brightness by day, a medium level for driving during the night and a lower level when at a standstill during the night, so as not to dazzle other road users. This light control is especially pleasant for other car drivers when stopping at traffic lights or in traffic jam situations, as they are met by a pleasant, dazzle-free brake and turn signal lamp.
