Can a 12 volt pool light kill you?
Thereof, are 12v pool lights safe?
The 12V lights are safer when installed properly by a licensed electrician. ALWAYS get a permit when performing electrical work in your pool, pool lamp replacements included. A permit may cost some money, but it means that someone will have to check your work and be sure that it is safe.
In this regard, can a pool light electrocute you?
Pool lighting: When pool lights have not been correctly bonded or grounded, they can send electricity directly through the water and shock those in the pool. As a general rule of thumb, any pool feature that is connected to power and placed underwater poses a hazard.
If you can reach the screw holding the light assembly in place from outside the pool, you don't have to get into the pool to change the light. Do I have to drain a pool to change the light bulb? You do not have to drain the pool if you can remove the light assembly.
