AB  - The purpose of this paper was to initiate broad research aimed to establish the preferred color of light of LEDs from a driver's point of view. Two street lighting installations (one with 3000 K and the other with 4000 K LEDs) were evaluated both objectively and subjectively. The objective evaluation, realized using a CCD camera, included detection of small targets and pedestrians. A slight advantage was identified for the 3000 K lighting installation regarding both types of target. As for subjective evaluation (realized through a questionnaire), the task of the participants (drivers) was to choose the more appropriate between the two lighting installations regarding six lighting parameters, as well as the overall visibility. The 3000 K LED installation was evaluated as a better solution for most analyzed parameters, as well as for the overall visibility. However, only the results regarding the color of the light (in favor of the 3000 K LEDs) and the detection of small light-colored obstacles (in favor of 4000 K LEDs) were convincing, which was confirmed by the statistical analysis. Due to the obtained mild preference for the 3000 K LEDs and several limitations/challenges of the conducted surveys, it was concluded that additional research is needed in order to decide on the preferred color of light of LEDs from a driver's perspective.

AB  - In order to compare drivers' subjective impressions when exposed to high-pressure sodium versus LED street lighting, an experiment was conducted on a Belgrade street. All general requirements for an adequate comparison of subjective impressions, equal luminances being the most important, were fulfilled. A survey was conducted using a questionnaire, which the respondents filled out immediately after driving through both zones of the illuminated street. The respondents, who were young drivers (students), aged 20-25 years, were asked to select the more appropriate of the two installations regarding seven lighting parameters as well as giving their overall impression. The two regimes for which the survey was done gave opposite results. In the normal regime, where both installations had the same photopic luminance, the LED installation was evaluated as a better solution by a majority of the respondents for most of the analysed parameters. In the mesopic regime, where both installations had the same mesopic luminance, most of the respondents judged that the high-pressure sodium installation was the better choice.
