All 8 of my outdoor landscape lights went out at the same time.
I thought it was the transformer, so I replaced it today, but the lights did not come back on. What else could cause them all to stop working at the same time?
They are not solar, they are electrically wired. The transformer is a black box to which the individual lights are wired and which plugs into the electrical outlet. It is also called a power pack.
They have little solar cell batteries inside the top of the lantern.
Rechargeable Batteries For Solar Lights
The majority of solar lights operate using one or more AA size Ni-Cad rechargeable batteries. We recommend these are replaced every 1-2 years or as found necessary. A defective battery is often the cause of a solar light malfunctioning or inefficient performance.
Open the link below/and see if you have the instructions around anywhere or go find a set at the store where you bought them and see which battery.

P.S. EDITED:you might want to check the lines to make sure that one of the lines didn’t get cut or break. Or even check the outlet for the transformer or your breaker switch.
