>Florida Department of Transportation officials told NBC 6 News the change in color is due to a manufacturing defect related to the filter in the light. The issue is related to a specific brand and model of LED fixtures.
The issue is not just in South Florida, according to FDOT, but across the state and around the country. The average cost to retrofit each light fixture and bulb? Just over $1,400.
FDOT said 137 fixtures would be replaced in Broward and 101 fixtures would be replaced in Miami-Dade as they are covered under warranty. However, due to supply chain issues the replacements have been delayed.
