BAT Blinking blue LED


I have just noticed that the front blue LED on my left BAT VK150SE amp is blinking. All 4 green LED's are turned on and the amp is working. Anybody knows if this blinking LED denotes a serious problem? Should I turn off the power and send it to service? Please help!

Thank you for the reply. It is good to know that it does not affect the operating condition of the amp.
I had the same thing & BAT sent me a replacment bulb. Very simply to install, but I haven't gotten around to it yet, so I can't say for sure that it will solve the problem.
