The first night test of the “smart crosswalk” at Hua Hin Market was a failure as 32 solar lamps embedded at the zebra cross-walk failed to emit enough light to make the crosswalk easily visible, a senior highway official said on Thursday.

The Highway Department along with a private firm have installed solar-cell lamps on a pedestrian crossing at the Hua Hin Market as part of the “smart crosswalk” project for 14 southern provinces.
