I have 6 Intellibrite LED lights in the pool. One of the lights turns on with the rest of the lights but after about 5 seconds it turns off. When you look at it you can see three red LED lights dimly lite in the unit. The rest of the lights are working perfectly. Do you think this is a unit that has gone bad or could it be a wiring issue. Just seems odd that it fires up then goes out. Thanks.
