Normally the housing would not have problem while the cooling and waterproof would not have problem , most problems happen to the driver or LEDs .

While driver and LEDs have problems , we have to replace the damage parts , the replacements could get from the market or producer .

If the driver damaged , the new driver should have same input voltage , same output voltage and current , or the street light would not work . For example , while the old driver output is 58V 2A , the new driver is 36W 1A , after replacement , the LED street light would not work , or could work but couldn't have same performance as before.

If the LEDs failed , have the replace the whole LED board , only replace the damaged LEDs need specially tools and knowledge . Only the replace the LED board , if not from the producer , would be very hard to find LED PCB that have same size , hole position , and LED quantity , sery and parreal , the best way is to ask the producer to offer replacements , and tell them the product model and the character on the PCB .
