This is the first of the four floodlights to be erected, with the second following shortly.
For safety reasons, due to its proximity to the Metrolink tram lines, this floodlight was erected overnight on the site of the old scoreboard that was demolished at the end of last year.
The final two floodlights will be put in to position following the Kings of Leon and Bon Jovi concerts that take place at Old Trafford in late June.
All four lights will be used for the first time at Lancashire's last two Friends Life t20 matches against Warwickshire Bears on Wed July 13th and Northants Steelbacks on Friday July 15th.
