Same here, I installed them when the weather was still in the 80's...mine has improved to about 85/15 (new harness and delay switch).
The only thing I can think of that even remotely makes sense is the initial current draw of the ballast. With both coming on at the same time, it may be tripping one of them. I may have to try something like delaying one of the lights so that they come one one at a time and see if that works, but that wont be for a while....the ice storm is here this weekend, so I can deal with it for now, but I would like to find a fix.
