Looking for some information to trouble shoot the light switch on my Yukon Arctic spa, 2 wks old. The lights are not coming on althought the top control does indicate that I have accessed this option. After a few minutes, the lights do come one with less intesity and do not change colour. Do I need new light bulbs? Is this a loose wire problem? I already had one reconnection required to get the Onzen working. The delivery crew did not plug in properly. Now that I have the right chemistry and sanitizer levels, I need a little light in the hot tub. Any sugestions?
